Description of Pin Function
Pin No. Symbol Pin Name Function and Operation Outputs common signals to LCD panels. Through a matrix with pins S1 to S18, a maximum of 72 segments can be displayed. Three levels, VLCD, VEE (1/2 VLCD ), and GND, are output at 62.5 Hz every 2 ms. VEE is output after system reset and CLOCK STOP are released, and a common signal is output after the DISP OFF bit is set to "0". These pins can be programmed as output ports (Note 1). Segment signal output terminals for LCD panel. Together with COM1 to COM4, a matrix is formed that can display a maximum of 72 segments. VEE is output after system reset and CLOCK STOP are released, and a common signal is output after the DISP OFF bit is set to "0". All pins from S1 to S10 can be programmed as output ports (Note 1), and all pins from S11 to S18 as I/O ports, in units of pins. When the pins function as output ports, VLCD pin potential and GND potential are output to them. When the pins function as I/O ports, drain output is N-ch open. Because power is supplied from VLCD for the I/O ports, up to VLCD voltage (3 V) can be applied. P8-0/S13~ 15~22 P9-3/S18 LCD segment An instruction increments the data ports output/ I/O port 8, 9 (OT1 to OT14) by 1 every time data are accessed. Therefore the ports can be used for external memory address signals, facilitating data access. Note: After system reset, the output port pins are set to LCD output, the I/O port pins to I/O port input. Remarks

4-bit I/O ports, allowing input and output to be programmed in 1-bit units. The I/O ports are N-ch open drain. Up to 3.6 V can be input. Even at low voltage, N-ch high output current (2 mA typ.) can be obtained. These pins also function as serial interface circuit (SIO) input/output pins. P3-0 I/O port 3 There are two types of serial interface circuit: SIO1 allows 4 or 8-bit input/output and SIO2 allows 26-bit serial data input. SIO1 inputs data of SI pin serially with the edge of the clock of SCK pin, and outputs it to SO pin. Internal (SCK = 37.5 kHz), external, or rising/falling shift can be selected as the clock (SCK) for serial operation. The SO pin can be switched to serial input (SI), facilitating LSI control and communication between controllers. Setting "1" in the SIO2 bit sets the SCK pin to the SIO2 clock input and the SI/SO pin to SIO2 data input. A synchronization circuit is built-in for SIO2. When SIO interrupts are enabled, an interrupt is generated after SIO execution or by SIO2 operating clock input and the program jumps to address 4. All SIO inputs use built-in Schmitt circuits. SIO and all controls are programmable. 4-bit I/O ports, allowing input and output to be programmed in 1-bit units. 28 P4-0/BUZR I/O port 4 /Buzzer output The P4-0 pin is also used for buzzer output. The buzzer output can select 8 kinds of 0.625 to 3-kHz frequencies with 4 modes: continuous output, single-shot output, 10 Hz intermittent output, and 10 Hz intermittent at 1 Hz intervals output. SIO, buzzer, and all associated controls can be programmed.

Pins P5-0 to P5-3 can also be used for analog input to the built-in 6 bit, 4-channel AD converter. The conversion time of the built-in AD converter using the successive I/O port 5 comparison method is 280 s. The /AD analog voltage necessary pin can be programmed to input AD analog input in 1-bit units. Up to the doubled voltage VDB (VDD x 2) can be input as the AD input voltage. I/O ports are N-ch open drain output. Up to the VDB voltage can be applied to the AD input pins. The AD converter and all associated controls are performed via sortware. 1-bit output port, normally used for muting control signal output.

Pin No. Symbol Pin Name Function and Operation Input pin for request/release hold mode. Normally, this pin is used to input radio mode selection signals or battery detection signals. Hold mode includes CLOCK STOP mode (stops crystal oscillation) and WAIT mode (halts CPU). Setting is implemented with the CKSTP instruction or the WAIT instruction. To request Clock Stop mode, either L-level detection on the HOLD pin or forced execution can be programmed. The mode is released by H-level detection on the HOLD pin or input change, respectively. Executing the CKSTP instruction stops the clock generator and the CPU, resulting in entry to memory backup state. In memory backup state, current dissipation becomes low (1 A or less) and the display output/CMOS output ports automatically become L level and N-ch open drain output is set toOff. Regardless of this input state, Wait mode is executed in order to lower power dissipation. Either operation of the crystal oscillator only or CPU suspension can be programmed. For operation of the crystal oscillator only, all displays are at L level and other pins are in hold state. For CPU suspension, the CPU stops and all others retain their states. Wait mode is released by changing HOLD input. The P34 pin is also used for external interrupt input. When interrupts are enabled and a 13.3 to 26.7-A pulse or longer is input to the pin, interrupt INTR1/2 is generated and the program jumps to address 1/2. Input logic or rising/falling edge can be selected for each input interrupt. The internal 8-bit timer clock input can be selected as input to the pins. When the count value reaches the specified value, an interrupt is generated (address 4). The pin is also used for input of an 8-bit pulse counter. Input rising/falling or upcount/downcount can be selected for the counter. Remarks

Pin No. Symbol Pin Name Function and Operation IF signal input pin for the IF counter to count the IF signals of the FM and AM bands and to detect the automatic stop position. The input frequency is between 0.3 to 12 MHz. A built-in input amp. and C coupling allow operation at low-level input. The IF counter is a 20-bit counter with optional gate times of 1, 4, 16 and 64 ms. 20 bits of data can be readily stored in memory. In Manual mode, gate On/Off or CR oscillator clock frequency count can be performed using an instruction. The input pin can be programmed for use as an input port (IN port). In this case, the pins are CMOS input. They can count input clocks using the IF counter. IFin1 also functions as an external interrupt input pin. When interrupts are enabled and a 13.3 to 26.7-A pulse or longer is input to IFin1, an interrupt is generated and the program jumps to address 1. Input logic or rising/falling edge can be selected for the input interrupt. The internal 8-bit timer clock input can be selected as input to the pin. When the count value reaches the specified value, an interrupt is generated (address 4). Note: When a pin is set to IF input, the input is at high impedance in PLL Off mode or if the pins are not used for input. Pins to which power is applied. Normally, VDD = 0.9~1.8 V is applied. 27, 39 VDD In backup state (at execution of the CKSTP instruction), current dissipation drops (1 A or less) and the power supply voltage can be reduced to 0.75 V.

Pin No. Symbol Pin Name Function and Operation For FM input, mode can be switched between 1/2 + Pulse Swallow VHF and FM mode. For AM input, mode can be switched between Pulse Swallow (HF) and Direct Dividing (LF) mode. Normally, local oscillation output (Voltage-Controlled Oscillator: VCO output) of 80 to 230 MHz is input in VHF mode; 60 to 130 MHz in FM mode; 1 to 30 MHz in HF mode; 0.5 to 8 MHz in LF mode. A PLL can be configured using an external prescaler. In such a case, set the pin to LF, and connect the prescaler divider output to the OSCin input pin and the PSC input to the P2-3 (PSC) output pin. With an input amp incorporated, capacitive-coupling, small-amplitude operation is supported. Note: The input is at high impedance in PLL Off mode. PLL phase comparator output pins. Tristate output. When the program counter divider output is higher than the reference frequency, H level is output; when lower, L level; and when they match, high impedance. For the phase comparator power supply, a 1.5-V constant voltage supply (Vreg pin) is used. Even if the power supply voltage drops, a stable PLL can be configured. The DO/OT pin can be programmed to high impedance or as an output port (OT). Note: For tristate output, the H-level output uses a constant voltage supply. When H-level output current is required, Toshiba recommend using an external power supply. Phase comparator constant voltage supply. When the phase comparator output is tristate output, a constant voltage supply of 1.5 V (typ.) is output to the pin. For this output, connect a stabilizing capacitor (0.47 F typ.). Constant voltage On/Off can be programmed. Because half the voltage potential can be switched to AD converter A/D input, it can be used to detect how much battery remains. At PLL operation, the constant voltage is used for H level phase comparator output. Thus, when H level output current is required, Toshiba recommend using an external power supply. Externally apply 1.8 to 3.6 V to the pin. Input pin for system reset signals. 54 RESET Reset input RESET takes place at low level; at high level, the program starts from address "0". Remarks

The oscillator stops oscillating during CKSTP instruction execution. Crystal oscillator pin The VXT pin is the power supply for the crystal oscillator. A stabilizing capacitor (0.47 F typ.) is connected. Usually, the clock of a crystal oscillator is used for the clock for peripheral equipment. Through programming, the built-in VCO can be changed to CPU and CPU only operation can be accelerated. Voltage doubler boosting output pins. The VDB pin doubles the VDD pin voltage using the voltage doubler boosting capacitor between C1 and C2. The doubled voltage is used for the AD converter and constant voltage circuit (Vreg, VEE) power supply. The VEE pin supplies a constant voltage of 1.5 V from the VDB voltage. The voltage is doubled (to 3 V) using the voltage doubler boosting capacitor between C3 and C4. The doubled voltage is then supplied to the VLCD pin. The VEE potential and the VLCD potential are used to drive the LCD. Connect a stabilizing capacitor between the VDB pin and GND (0.1 F, 10 F typ.), and between the VLCD pin and GND (0.1 F typ.). Connect a voltage doubler boosting capacitor (0.1 F typ.) between C1 and C2, and between C3 and C4. (Note) VLCD XOUT ROUT RfXT VDD XIN Remarks

Description of Operations
CPU
The CPU consists of a program counter, a stack register, an ALU, a program memory, a data memory, a G-register, a data register, a DAL address register, a carry F/F, a judgment circuit, and an interruption circuit.
1. Program Counter (PC)
The program counter consists of a 14-bit binary up-counter and addresses the program memory (ROM). The counter is cleared when the system is reset and the programs start from the 0 address. Under normal conditions, the counter is increased in increments of one whenever an instruction is executed, but the address specified in the instruction operand is loaded when a JUMP instruction or CALL instruction is executed. Also, when an instruction that is equipped with the skip function (AIS, SLTI, TMT, RNS instructions, etc.) is executed, and the result of this includes a skip condition, the program counter is increased in increments of two and the subsequent instruction is skipped. Furthermore, if interruption is received, the vector address corresponding to each interruption is loaded. Note: Addresses 0000H-0FFFH are reserved for the program memory. For this reason, access to addresses outside this range is prohibited.

2. Stack Register
A register consisting of 8 x 14 bits which stores the contents of the program counter +1 (the return address) when a sub-routine call instruction is executed. The contents of the stack register are loaded into the program counter when the return instruction (RN, RNS, RNI instruction) is executed. There are eight stack levels available and nesting occurs with both levels.

TC9329AFAG/AFCG
3. ALU
ALU is equipped with binary 4-bit parallel add/subtract functions, logical operation, comparison and multiple bit judgment functions. This CPU is not equipped with an accumulator, and all operations are handled directly within the data memory.
4. Program Memory (ROM)
The program memory consists of 16 bits x 4096 steps and is used for storing programs. The usable address range consists of 4096 steps between address 0000H ~ 0FFFH. The program memory is divided into 4096 separate steps and consists of page 0 ~ 3. The JUMP instruction and CALL instruction can be freely used throughout all 4096 steps. In case of setting DAL bit (it arranges on I/O map) "0" (DAL ADDR3, (r) command), the program memory address 0000H ~ 03FFH (page 0) are used as data area and setting DAL bit "1" (DAL (DA) command), the program memory address 0000H to 0FFFH (page 0 ~ 3) are used as data area. The 16 bit contents of this can be loaded into the data register by executing the DAL instruction. Note: An address outside of the program lop must be set when establishing a data area within the program memory.

5. Data Memory (RAM)
The data memory consists of 4 bit x 256 words and is used for storing data. These 256 words are expressed in row addresses (4 bits) and column addresses (4 bits). 192 words (row address = address 004H ~ 00FH) within the data memory are addressed indirectly by the G-register. Owing to this, it is necessary to specify the row address with the G-register before the data in this area can be processed. The address 00H ~ 0FH within the data memory are known as general registers, and these can be used simply by specifying the relevant column address (4 bit). These sixteen general registers can be used for operations and transfers with the data memory, and may also be used as normal data memories. Note: The column address (4 bit) that specifies the general register is the register number of the general register. Note: All row address (addresses 0H ~ FH) can be specified indirectly with the G-register. Note: The data memory is 256 words and 2 bits of the 6-bit higher ranks of G-register row address are used "0" (00H ~ 0FH address). Note: By using LD and ST instructionss, it can be addressed directly in 256 words (row address = 00H ~ 0FH) in a data memory.

TC9329AFAG/AFCG
6. G-Register (G-REG)
The G-register is a 4 bits register used for addressing the row addresses (DR = 4H ~ FH addresses) of the data memory's 192 words. The contents of this register are validated when the MVGD instruction or MVGS instruction are executed, and not affected through the execution of any other instructions. This register is used as one of the ports, and the contents are set when the OUT1 instruction from among the I/O instructions is executed. The 6-bit contents can be directly set by execution of STIG instruction. (Refer to the Register Port section.)
7. Data Register (DATA REG)
The data register consists of 1 16 bits and stores 16 bits of optional address data. This register is used as one of the ports, and the contents are loaded into the data memory in units of 4 bits when an IN1 instruction from among the I/O instructions is executed. ( Refer to the Register Port section.) Moreover, this register supports writing from the data memory and is used for evacuation/return processing of the data at the time of interruption.
8. DAL Address Register (DA)
The data register consists of 1 x 14 bits. If a DAL instruction is executed when the DAL bit is set to "1", 16 bits of the data of the free addresses in the program memory specified by this DAL address register are loaded. By the setting (DATA) DA bit to "1", the contents of data register (DATA REG) can be transmitted to DAL address register (DA). This register and a control bit are treated as a port, and are accessed by IN3/OUT3 instruction of an input-and-output instruction. ( Refer to section in Register port item)
9. Carry F/F (Ca Flag)
This is set when either Carry or Borrow are issued in the result of calculation instruction execution and is reset if neither of these are issued. The contents of carry F/F can only be amended through the execution addition, subtraction, CLT, CLTC instructions and are not affected by the execution of any other instruction. The carry F/F can be accessed by the IN1/OUT1 instruction of an input-and-output instruction. For this reason, an input-and-output command performs the evacuation and the return at the time of interruption between data memories. ( Refer to the Register Port section.)
10. Judgment Circuit (J)
This circuit judges the skip conditions when an instruction equipped with the skip function is executed. The program counter is increased in increments of two when the skip conditions are satisfied, and the subsequent instruction is skipped. There are 15 instructions equipped with a wide variety of skip functions available. ( Refer to the items marked with a "*" symbol in the Table Instruction Functions and Operational Instructions)
11. Interruption Circuit
An interruption circuit branches to each vector address by the demand from circumference hardware, and performs each interruption processing. (Refer to the interruption function section.)

I/O map
All of the ports within the device are expressed with a matrix of six I/O instructions (OUT 1 ~ 3 instructions and IN 1 ~ 3 instructions) and a 4-bit code number. The allocation of these ports is shown on the following page in the form of an I/O map. The ports used in the execution of the various I/O instructions on the horizontal axis of the I/O map are allocated to the port code numbers indicated on the vertical axis. The G-register, data register and DAL bits are also used as ports. The OUT1 ~ 3 instructions are specified as output ports and the IN 1 ~ 3 instructions are specified as input ports. Note: The ports indicated by the angled lines on the I/O map do not actually exist within the device. The contents of other ports and data memories are not affected when data is output to a non-existent output port with the execution of the output instruction. The data loaded from data memories when a non-existent input port has been specified with the execution of an input instruction becomes "1". Note: The outout ports marked with an asterisk (*) on the I/O map are not used. Data output to these ports assume the don't care status. Note: The Y1 contents of the ports expressed in 4 bits correspond to the data memory's low order bits and the Y8 contents correspond to the high order bits. The ports specified with the six I/O instructions and code No. C are coded in the following manner:
[K/L]
mn
(o) Contents of the selection port (indirectly specified data, 0-F [HEX])
I/O instruction's operand CN (0~F [HEX])
The six I/O instructions are coded with the digits 1 to 3

Clock Generator
The clock generator generates the standard clock used as the standard of the system clock supplied to a core-based CPU and circumference hardware. Through the program, it is possible to switch between an external crystal oscillation circuit and the built-in CR oscillation circuit as the CPU operation clock.
1. Crystal Oscillation Circuit
75 kHz crystal resonator is connected to the device's crystal resonator terminal (XN, XOUT) as indicated below. During normal operation, the oscillation signal is supplied to the clock generator, the reference frequency divider and other elements, and generates the various CPU timing signals and reference frequency.
(XOUT) 54 R X'tal = 75 kHz 55 (XIN) 56 (GND) 57
CO
X'tal
CI
Note: It is necessary to use a crystal resonator with a low CI value and favorable start-up characteristics. Be sure to adjust and set the external resistance and capacitor constant to the crystal resonator actually used.
2. CR VCO
Through the use of the built-in CR VCO, it is possible to raise the CPU processing speed. This will be utilized for high-speed processing in the required system. The OSCon bit controls the ON/OFF operation of the CR oscillation circuit; and if this bit is set to "1", the CR VCO starts operating. If the setting of the CPU Select bits is "0", the CPU operates on the 75 kHz for the crystal oscillator clock; if the setting is "1", the CPU operates on the CR VCO clock. The oscillation frequency of CR VCO (fCR) is 1 MHz (typ.); and a clock that divides this frequency by 1/2 or 1/4 can be used as the CPU operation clock. The CR VCO frequency serves as a system that can control the resistance of the CR VCO through the program so that factors, such as power supply voltage and the variations in the built-in capacitor and resistance can be changed. For this reason, it is possible to calculate the CR oscillation frequency using the IF counter. If used for the CPU clock, the frequency of the CR VCO is changed to the CPU operation clock after the CR VCO resistance is controlled and adjusted to the set-up frequency and the CR oscillation frequency is calculated using the IF counter. Moreover, the frequency changes with the change in power supply voltage from -15% to +10% of the set value, VDD = 1.5 V (i.e., from VDD = 1.1 V to VDD = 1.8 V). If a setting frequency with an accuracy greater than this range is required, be sure always to adjust the CR VCO frequency using the IF counter. The frequency setting range of CR VCO can be freely set up in the range 0.8 to 1.2 MHz. The resistance of the CR VCO, which has a standard value of 36 k (1 MHz), can be programmed to 16 levels, from 20 k to 50 k (in 2 k steps) and the value set using the data of 3 bits of OSC0-OSC3. The Freq Select bit sets the division value of the CR oscillation frequency. The frequency is fCR/2 if this bit is set to "0", and fCR/4 if the bit is set to "1". When the frequency is set to fCR = 1 MHz, the instruction executing time is compared with the 40 s for when the crystal oscillator clock is used. The instruction execution time is accelerated to 3/500 kHz = 6 s for 1/2 division mode, and to 3/250 kHz = 12 s for 1/4 division mode. Although the processing speed of the CPU is accelerated, other timing functions (such as that for the Timer, etc.) operate on the crystal oscillation frequency. The Ifin bit is a control bit for changing the CR oscillation frequency clock to the IF counter. If "0" is set, the IF counter starts calculating the IF (etc.); if "1" is set, the CR VCO frequency can be selected as the clock input of the IF counter. To calculate the CR VCO frequency, it is necessary to set the Prescaler IN bit to "1". ( Refer to IF counter item.) Moreover, the CR oscillation frequency clock can be output from the MUTE terminal, and used for external IC clocks and monitoring of the CR oscillation clock monitor. If the Test port 1 (L1F) is set to "5H", the CR VCO clock outputs from MUTE terminal. The setup and control of the frequency of the CR VCO is set using an OUT3 instruction for which [CN = 6~7H] has been specified in the operand

System Reset
The device's system will be reset when the RESET terminal is subject to the "L" level. The program will start from 0 address after about 100 ms of stand-by time have elapsed following system reset. Note: The LCD common output and the segment output will be fixed at their "L" level during system reset and during the subsequent stand-by period. Note: It is necessary to initialize through the program any of the internal ports shown in the above-mentioned I/O map that were not initialized after system reset. The mark on the I/O map after system reset indicates a port or bit set to "0" after system reset, while the mark indicates a port or bit set to "1". A port or bit with no mark is unfixed..

Back-up Mode
By executing the CKSTP instruction or WAIT instruction, three kinds of back-up mode can be activated.
1. Clock Stop Mode
Clock stop mode is a function that suspends system operations and maintains the internal status immediately prior to suspension at a low level of current consumption (under 1 A). Crystal oscillations suspended simultaneously and CMOS output ports and output terminals for LCD display purposes are automatically set at "L" level, and N-channel open-drain terminals are set to off status (high impedances) automatically. The supply voltage can be reduced to 0.75 V with clock stop mode. Suspension is activated at the CKSTP instruction execution address when the CKSTP instruction is executed. The next address is executed after approximately 100 ms of stand-by time when clock stop mode is cancelled. (1) Clock stop mode setting There are two types of mode setting for clock stop mode. The required setting is selected with the CKSTP MODE bit. This bit is accessed with the OUT2 instruction for which [CN = 6H] has been specified in the operand.
Y1 Y2 Y4 CKSTP mode 0: MODE-0 1: MODE-1 Y8
L26
MODE-0 Wtih this mode set, the clock stop mode is assumed if the CKSTP instruction is executed when the HOLD terminal is at "L" level. The same operations as the NOOP instruction will be assumed if the CKSTP instruction is executed when the HOLD terminal is at "H" level. MODE-1 With this mode set, the clock stop mode is assumed when the CKSTP instruction is executed regardless of the HOLD terminal level.
Note: The PLL will assume off status during execution of the CKSTPinstruction. Note: Before the execution of the clock stop instruction, be sure to access the HOLD input terminal and I/O port 1 input port and rest the 2 HzF/F. Without execution of this instruction, it may not be possible to enter clock mode even if clock mode is executed.
(2) Canceling clock stop mode
MODE-0 Clock stop mode is cancelled when specified in this mode by changing the "H" level of the HOLD terminal or the input status of the I/O port (P1-0~3) specified in the input port. MODE-1 Clock stop mode is cancelled when specified in this mode by changing the HOLD terminal or the input status of the I/O port (P1-0~3) specified in the input port.

2. Wait Mode
Wait mode suspends system operations, maintains the internal status immediately prior to suspension and reduces current consumption. There are two types of wait mode: SOFT WAIT mode and HARD WAIT mode. Operations are suspended at the address where the WAIT instruction was executed when the wait mode is activated. The next address is executed immediately after the wait mode is cancelled without entry to stand-by status. (1) SOFT WAIT mode Only the CPU operations within the device are suspended on execution of a WAIT instruction in which [P = 0H] has been specified in the operand. The crystal resonator and other elements will continue to operate normally at this time. The SOFT WAIT mode is efficient in reducing current consumption during clock operations when used in programs that include clock functions. Note: Current consumption will differ in accordance with execution time of CPU operation. (2) HARD WAIT mode The operations of all elements, with the exception of the crystal resonator, can be suspended by the execution of a WAIT instruction in which [P = 1H] has been specified in the operand. This enables even greater levels of current consumption reduction than the SOFT WAIT mode. It suspends the CPU operation. Note: The output port is maintained during HARD WAIT mode. All LCD display output terminals are fixed at "L" level and the voltage doubler circuit (VDB), LCD voltage regulator ciicuit (VEE) and LCD voltage doubler circuit (VLCD) operate. (3) Wait mode setting The wait status is assumed whenever the WAIT instruction is executed. Note: The PLL OFF status will be assumed during the wait mode. (4) Wait mode cancellation conditions Wait mode is cancelled when the following conditions are satisfied: When the input status of the HOLD terminal changes. When the input status of the I/O port specified in the input port (P1-0~3) changes. When the 2 Hz Timer F/F is set as "1" (only with the SOFT WAIT mode)

The HOLD terminal can be used as an input port. This bit loads into the data memory data input using the IN1 instruction for which [CN = 7H] has been specified in the operand. It is necessary to access this port prior to the execution of the CKSTP instruction when clock stop mode or wait mode is set. Note that, without accessing this port it may not be possible to enter clock stop mode even if this instruction is executed. While HOLD PLL off control bit is set to "1", PLL off mode result if HOLD terminal input goes to "L" level. Therefore setting to PLL off-mode can be done quickly during battery replacement. The bit is accessed with the OUT3 instruction for which [CN = 9H] has been specified in the operand. PLL off mode becomes active even if all reference ports are "1". ( Refer to the reference frequency divider item) Note: The HOLD input terminal is used as an INTR2 terminal. The same as data is output at the HOLD and INTR2 input ports.

Interrupt Function
The peripheral hardware that can use the Interrupt function has an INTR1 terminal, INTR2 terminal, Timer counter, and Serial interface. If this peripheral hardware fulfills the conditions, the interrupt request signal from the peripheral hardware is output, and the interrupt request is issued. On being received, each interrupt branches to a vector address determined by the interrupt factor, and the processing routine for the interrupt begins. Pretreatment and post-processing are necessary in the interrupt routine, before and after the normal Interrupt processing, to restore the same state that was in effect at the time the interrupt occurred. It is necessary to perform shunting and return of the register and indestructible data memory used by ALU to the data memory for Interrupt use.. When interrupt processing ends, the program is restored using the Return command for the Interrupt function. The INTR1 and INTR2 terminals are serve as IFin1 and HOLD terminals.
1. Interrupt Control Circuit
The Interrupt Control Circuit consists of an interrupt permission flag, an interrupt latch, and an interrupt priority circuit block. This control performs setup and control through the OUT2/IN2 instructions. (1) Interrupt enable flag The interrupt enable flag has a master permission flag and individual permission flags corresponding to each interrupt factor. An individual enable flag sets the interrupt prohibition/permission according to the interrupt factor. A master enable flag is a flag for prohibiting or permitting all Interrupts. If these enable registers are set to "1", permission takes effect; if they are set to "0", prohibition takes effect.. An individual enable flag is accessed through the OUT2/IN2 instructions for which [CN 8H] has been specified in the operand. A master enable flag can perform permission/prohibition by execution of an EI/DI instruction. Interrupt is prohibited by execution of a DI command, and enabled by execution of an EI command. At this time, interrupt is enabled during execution of the EI command and DI command in the program. If an interrupt request is received, the master enable flag is reset to "0" and all interrupts are prohibited. On execution of the interrupt return command, the flag is set to "1". A master enable flag is read into the data memory using an IN2 command for which [CN = 7H] has been specified.

(2) Interrupt latch If an Interrupt request generates, the interrupt latch is set to "1". If Interrupt is enabled, the CPU will be requested to receive the Interrupt, and the process will branch to the Interrupt routine. If the Interrupt is received at this time, the Interrupt latch is reset by data "0" automatically. Interrupt latch data can read by the program and the existence or nonexistence of an Interrupt occurrence can be determined on an individual basis. In accordance with the Interrupt request, the Interrupt latch that was set to "1" is reset to "0"; in this way, it is possible to cancel or initialize the Interrupt request.

2. Interrupt Reception Processing
The interrupt request is retained until the interrupt is received or the interrupt latch is reset to "0" by system reset operation or by the program. The interrupt reception operation is as shown below. If the interrupt conditions are fulfilled, each item of peripheral hardware outputs each interrupt request signal and sets the Interrupt latch to "1". The Interrupt latch of the interrupt factor received resets to "0" if the interrupt enable flag corresponding to each interrupt factor and the master enable flag are set to "1". The interrupt master enable flag resets to "0" and interrupt is prohibited. The contents of a stack pointer are made -1. The contents of the program counter (PC) are shunted to the stack register. In this case, the contents of the program change to the next address after the point at which the interrupt was received, or the next address after the point at which the interrupt was permitted. The contents of the vector address corresponding to the received interrupt are transferred to the program counter. The contents of the vector address are executed. Steps ~ are executed within one instruction cycle. This instruction cycle is called the "Interrupt Cycle" Note: The stack pointer is a pointer for which an 8-level stack register is specified.

3. Return Processing from Interrupt Processing Routine
A special command, the RNI instruction, is used to return to the processing state that was in effect before the interrupt was received. With execution of the RNI instruction, the following processing is executed step-by-step automatically.
The contents of the address stack, specified by the stack pointer, are returned to the program counter. Set the Interrupt Master Enable Flag to "1" to activate the enable state. +1 is applied to the contents to the stack pointer.
The above-mentioned RNI instruction processing is performed in one instruction cycle.
4. Interrupt Processing Routine
The interruption is received regardless of the program being run when the interrupt request is issued if this is the program area where the interrupt is enabled. Therefore, to restore the base program after the interrupt processing is completed, it is necessary to return to the state in which interrupt processing was not being performed. For this reason, it is necessary to perform the shunting and return operations within the interrupt processing routine, at least for those items such as the register and data memory that can be operated within the interrupt processing routine. Shunting processing In the execution of the shunting processing, it is essential that a carry flag be shunted. If interruption is received during the execution of arithmetic or similar operations, the contents of the carry flag (CY), etc., will change, resulting in the program making incorrect decisions. For this reason, the contents of the carry flag are shunted in the data memory once through the IN1 instruction in the data of the carry flag of the I/O map. The contents of the data memory used by the interruption processing routine and the contents of a general register are also made to shunt if needed. Furthermore, when MVGD, MVGS or DAL instruction is used in the interrupt routine, it is necessary to shunt the contents of the G-register or the DAL address register. (2) Return processing Return processing should do the opposite to the above-mentioned shunting processing. Since, when the interrupt is received, the interrupt master enable flag is reset to "0", it follows that before receiving the interrupt, the interrupt master enable flag must have been "1". For this reason, the RNI instruction is executed and a master enable flag is returned. (1)
5. Multiplex Interrupt
Multiplex Interrupt is a method of processing others interrupt during interrupt processing. As shown in the figure, the other interrupt factor C or D is processed during the interrupt processing of interrupt factors A and B. In this process, the depth of the interrupt is called the interrupt level.

TC9329AFAG/AFCG
Caution is required for the following points when using multiplex interrupt.
The priority of interrupt factors Restriction of the address stack level used at the time of interrupt request issue Shunting processing of the carry flag, the data memory, etc.
(1) Priority of interrupt factor In this priority ranking, the processing of interrupt C must be given priority even if the interrupt processing of A or B is in progress; and the processing of D must be given priority even if the interrupt processing of C is in progress. The necessity of determining priority in the handling of multiple interruptions can be illustrated as follows. Suppose, for example, there are the interruption factors A and B. For factor A, a request is generated about every 10 ms and the interrupt processing time is 4 ms; for factor B, a request is generated about every 2 ms and the interrupt processing time is 1 ms. If no priority were applied to A and B, then a request for interrupt A that came in during the processing of interrupt B could lead to interrupt A being processed, resulting in the processing of interrupt B being repeatedly stopped. Such a case requires a program that establishes the priority A B, not only prohibiting interrupt A during the processing of interrupt B but also enabling the reception of interrupt B during the processing of interrupt A. As explained in the item on the interrupt priority circuit block, when all individual enable flags are set to "1" (enable state), the priority of the hardware can be changed by manipulating the individual enable flags in the program. As a rule, received interrupts and low-priority interrupts are prohibited, and high-priority interrupts are enabled in the interrupt processing routine. Restriction of address stack level As explained in the item on interrupt reception processing, when an interrupt request is issued, the return address is shunted automatically to the address stack. As explained in the item on registers, an address stack is also used for execution of sub-routine call instructions on eight levels. For this reason, if the interrupt level and sub routine call level exceed eight levels, the contents of the return address recorded from the first address stack are destroyed. Therefore restriction is necessary. Shunting processing When using the Multiplex Interrupt function, it is necessary to secure a shunting area for shunting processing separately for each interrupt factor.

External Interrupt and Timer Counter Function
There are two types of external interrupt: that using the INTR1 terminal and that using the INTR2 terminal. Interrupt requests are issued by the rising or falling edge of a signal applied to these terminals. The timer counter is an 8-bit binary counter and has the function of timer and external clock timer. The input of the external clock timer function is used as an external interrupt terminal (INTR1, INTR2).
1. External Interrupt Function
There are two input terminals for external interrupt, INTR1 and INTR2; and an interrupt request is issued on detection of the edge of these inputs. There is a noise canceller for the input: a noise removal clock uses a frequency of 75 kHz, and any pulse under this frequency is removed as noise. The IE bit is an enable bit which permits 8-bit timer counter operation, and interrupt and external interrupt requests. It is possible to select either the rising or falling edge as the input edge for each terminal. Usually, this bit is set to "1". These controls are accessed using an OUT2 instruction for which [CN 7H] has been specified in the operand. The program will branch to address 0001H on receipt of an INTR1 interrupt, and to address 0002H on receipt of an INTR2 interrupt. These terminals are used as input ports and the input status can be read into the data memory by execution of an IN2 instruction for which [CN 7H] has been specified in the operand.

Note: An interrupt request may be issued if an edge is changed using POL bits. For this reason, when changing an edge, be sure to prohibit interruption beforehand. After making the change, reset the interrupt latch and return to normal operation. Note: The INTR1 terminal and INTR2 terminal are used as IFin1 terminal and HOLD terminal respectively. If using only the INTR1 terminal be sure to set IF1/INTR bits (L16) to "0". Also, the same data is output at the HOLD input and INTR2 input port.

2. Timer Counter Function
Timer counter are consists of 8-bit binary counter, counter coincidence register, digital comparator and controlled the control circuit. If timer counter is coincided with the contents of counter coincidence register, timer counter is outputted a coincidence signal pulse and interrupt request is done by inputting timer clock to 8-bit binary counter timer clock. Reset of Timer counter is possible with a coincidence pulse and a program, and it can perform enable and prohibition of reset by the coincidence pulse. As a clock of timer, it can be selected INTR1/2 input and an instruction cycle and 1 kHz.

At this time, control bit is set to 1 kHz or an instruction as timer clock, "0" to GT bit and "0" (it does not reset) to CR bit. Timer coincidence data is Timer time = IDn (coincidence data) x Timer clock cycle It sets up the data which corresponding to time. In addition, although an external terminal can be used for Timer clock, a clock frequency should use the frequency below 25 kHz. If GT bit is setup "1", it can be also be integrated of an external clock.
It is used by inputting more than 40 s cycle at the time of an external clock input. Timer clock

Programmable Counter
The programmable counter consists of two modulus prescalers, a 4-bit + 13 bit programmable counter and a port to control these elements. The programmable counter controls the ON/OFF functions for the contents of the reference port and HOLD input status. By using external prescaler (TD6134AF/TD7101/04F) or 1 chip tuner IC that is built-in for 1/16 prescaler (TA2142FN), it's possible to reduce the emission from the tuner portion and consumption current.

2. Division Method Setting
The pulse swallow method or direct method are selected using the HF and FM bit. The power control bits (PW0/1) control the gain of the amplifier and prescaler (1/2 1/15*16). Although the power bit in each mode has five methods, set it up as shown in a table. By using the single-chip tuner IC that is built-in for the 1/16 prescaler (TA2142FN), set the LF mode and set the division value after the 1/16 division frequency.

VCO input serves as each of operation mode common terminal. Note: If it becomes PLL off-mode, all programmable counter parts will be stopped. The contents of each control port are held at this time.
Reference Frequency Divider
The reference frequency divider divides the oscillation frequency of the external 75 kHz crystal and generates the following seven types of PLL reference frequency signals; 1 kHz, 3 kHz, 3.125 kHz, 5 kHz, 6.25 kHz, 12.5 kHz and 25 kHz. These signals are selected with reference port data. The selected signal is supplied as a reference frequency for the phase comparator as described below. Also, the PLL is switched on and off with the contents of the reference port.
1. Reference Port
The reference port is an internal port for selecting the seven reference frequency signals. This port is accessed using an OUT1 instruction for which [CN 5H] has been specified in the operand ( L15). Operations for the programmable counter, the IF counter and reference counter are suspended; and the PLL assumes the off mode when the contents of the reference port are all "1". As the frequency division setting data for the programmable counter is updated when the reference port is set, it is necessary to set the frequency division number of the programmable counter prior to setting the reference port.

Phase Comparator and Lock Detection Port
The phase comparator compares the difference in phasing between the reference frequency signal supplied from the reference frequency divider and frequency division output of the programmable counter and outputs the result. It then controls the VCO (voltage control oscillator) via a low pass filter in order to ensure that the two frequency signals and the phase difference match. In order to use a phase comparator and a charge pump output are constant voltage Vreg potential (1.5 V), it is possible to stabilized phase comparison even if VDD potential was set to 0.9 V. The DO terminal can also be used as a general-purpose output with the Do control port.

M0 and M1 bit of DO control ports are perform a general-purpose output port setup of DO output, and a setup of high impedance. The power supply of a phase comparison and a charge pump output circuit is using Vreg terminal. The Vreg terminal is output constant voltage of 1.5 V and "H" level of charge pump output is output Vreg terminal. For a reason, phase comparison operation power supply voltage was stabilized by 0.9 V is possible. The operation control of Vreg Constant voltage is controlled by Vreg ON bit (L3BA), if the bit is set "0", the Vreg terminal potential is output VDD level and set "1", it becomes 1.5 V Constant voltage potential For this reason, it is set "1" at the time of PLL on mode and set "0" at the time of PLL off-mode. Unlock F/F detects the phase difference of a programmable counter division output and reference frequency to the timing from which about 180 degrees of phases shifted. When a phase does not suit at this time (that is unlock status), unlock F/F is set. The unlock F/F status is reset whenever the UNLOCK RESET bit is set as "1". It is necessary to access to UNLOCK F/F after establishing more time than is required for the reference frequency cycle after the unlock F/F has been reset in order to detect the phase difference with the reference frequency cycle. It is for this purpose that the enable bit has been made available, but the unlock F/F must not be accessed until after it has been confirmed that the unlock enable has been set at "1".
Note: When PLL off mode is set during the DO output setup, the output of this terminal becomes as high impedance. In DO terminal, when PLL off-mode or the clock stop mode is set up at the time of a general-purpose output port setup, this output state is held.

Note: When it is set as IF input, in PLL off-mode, IF input amplifier is turned off in PLL-off mode. In using IF counter in PLL off-mode, it sets it as an input port (CMOS input). Note: The input amplifier un-chosen by IF1/ 2 bit. If input amplifier turns off, this input will serve as high impedance.
(3) IF counter automatic mode A setup in the auto mode of IF counter is set "0" to MANUAL bit and gate time is set up according to the frequency band to measure. If the STA/ STP is set "1", operation of IF counter will be started and the set-up clock in gate time will be input, and this number of input pulses is counted and it ends. An end of the calculation of IF counter can be judged by referring to BUSY bit. When more 220 pulses are input for a total numerical value, OVER bit is set to "1". BUSY bit and OVER bit are judged "0" and the frequency input can be measured by taking in IF data of F0-F19. IF counter manual mode By internal time base (10 Hz etc.), it is used when gate time is controlled and it measures frequency. The manual mode is set "1" to MANUAL bit. At this time, a gate time setup serves as don't care. In STA/ STP bit is set to "1", it starts calculation. In STA/ STP bit is set to "0", it will end and calculation will take in data by the binary.

LCD Driver
The LCD driver uses a 1/4 duty and 1/2 bias drive method (62.5 Hz frame frequency). The common output outputs the VLCD, VLCD/2 (VEE) and the GND electrical potential, and the segment output outputs the VLCD and GND electrical potential. A combination of four common outputs and 18 segment outputs enables a maximum of 72 segments to be illuminated. The S11 to S18 segment output pins for the LCD driver can also be used as I/O ports on being set to function as I/O ports after system reset. The I/O port and segment output can be changed using bit units. All LCD output pins (COM1-S14) can be changed to output ports. The LCD driver is incorporates a constant voltage circuit (VEE = 1.5 V) for display purposes and a voltage doubler circuit (VLCD = 3.0 V). The voltage doubler (VDB), which raises the power supply voltage to twice its level, is used for the constant voltage circuit for the display (VEE). For this reason, it is even possible to stabilize the LCD display at a power supply voltage of 0.9 V.

The LCD driver control port consists of the segment data selection port and the segment data port. These ports are accessed using an OUT2 instruction for which [CN = DH~FH] has been specified in the operand. The segment data for the LCD driver is set through the segment data ports (L2E, L2F). The LCD display will be extinguished when the segment data port is set to "0", and will be illuminated when the port is set at "1". Also, the segment-2 data (L2FF) specified with FH in the segment selection port becomes the DISP OFF bit and LCD OFF bit without setting of the segment data. It is possible to extinguish the entire LCD display using the DISP OFF bit without setting the segment data. If this bit is set to "1", the common output and segment output are fixed to "L" level and the entire LCD display is extinguished. The segment data is retained at this point, and the previous display appears on the LCD if the DISP off bit is set to "0". In addition, rewriting of segment data is possible during DISP OFF. Moreover, after reset and CKSTP instruction execution, the DISP off bit is set to "1". The LCD off bit can set all LCD output terminals to serve as output ports. For the LCD display, this bit is set "0". ( Refer to the output port item) The terminals S11 to S18 terminal are used as I/O Ports. This control is done a segment/IO port select port (L2F6, L2F7). Set to "1", the port will become segment output port and set to "0", it will become an I/O Port. ( Refer to the output port item) These data is divided and undirected setting by data selects port (L2D). The data of a specification port to set a segment data port to beforehand is set, and the data port corresponding to it is accessed. A data select port is +1 increment whenever accessing data port (L2E, L2F). For this reason, after setting up a data selection port, it can set up continuously.
Note: The data select port is +1 increment automatically by accessing L2E, L2F, L3B, K3B on I/O map.

Serial Interface (SIO1/2)
There are two kinds of serial interface: SIO1 and SIO2. SIO1 is the serial I/O port, which transmits and receives data (4 bits or 8 bits) in synchronization with an internal or external serial clock. The SI, SO, and SCK terminals transmit and receive together with the extension LSI and microcomputer, etc. Interruption is issued when the serial interface stops operating. All outputs are Nch open drain outputs. SIO2 inputs 26-bit data serially in synchronization with an external serial clock. SIO2 has a function for decoding the input serial data, and interruption is issued for every input serial clock edge.

Serial clock (SCK) shift operation is performed on the rising edge if the edge bit is set to "0", and on the falling edge if the edge bit is set to "1". SCK-INV bit is set the bit of serial clock output from "H" or L". In case of setting "0", it starts shift operation from "H" output, and setting "1", it starts shift operation from "L" output. These bits perform serial operation in accordance with the settings as shown in the following table. Make the settings in accordance with the controlling serial format. SCK-I/O bit is setup the input-output of serial clock. Usually, when this product is used as a master, t "1" to SCK-I/O bit and then it used as serial clock output and in the case of a slave, set to "0" and then it used as serial input.

Example for serial input-output operation
Serial interface operation monitor The operational status of the serial interface is determined by referencing the BUSY, COUNT, and SIO F/F bits. As the BUSY bit becomes "1" during SIO operations, control data switching and serial data access is performed when the BUSY bit is "0". It interrupts in falling of BUSY bit and a demand is published. The COUNT bit determines whether the sending/receiving of data has been performed in multiples of four. The bit is set to "0" if shift operation was performed in multiples of four, and to "1" if not. . The SIO F/F bit is set to "1" when the SCK terminal starts shift operation. Both COUNT bb it and SIO F/F bits are reset to "0" when "1" is set in the STA bit. These two bits are mostly used when the SCK terminal sets external clocks (slave mode). An external clock is input and it can be judged to be the information that serial data was transmitted and received whether operation was performed normally. Usually, since interruption is published, interruption processing performs a serial interface end. STA bit STA bit is used to start serial interface operation. Serial operation is started whenever the STA bit is set to "1". If the STA bit is set to "1", serial output data will be transmitted to a shift register, and the COUNT bit and SIO F/F bit will be reset. A serial clock is output for an internal SCK setting; and a state of waiting for the serial clock input will take effect in the case of an external setting.

For this reason, the contents of the data set to serial output data and those of the serial input data are not in agreement. Note: All serial input terminals are the Schmitt input type. Note: The output of the SO terminal and the serial clock output of SCK terminal are Nch open drain outputs. For this reason, connect pull-up resistance. In addition, be sure to use a pull-up potential of 3.6 V or less.

The data port of the serial interface 2 (SIO2) is constituted of 16-bit information data (K3B8~B), 10-bit check data, 10-bit offset data and 4-bit decoding data (K3B7). In 26-bit serial data, serial data of 16-bit are information data and 10-bit are check data. As shown in the above-mentioned table, the data that took the exclusive logic sum of each bit of 26-bit data turns into offset data. Furthermore, when the offset data is specialized in the above -mentioned, the data of 1~6h and Bh are output as 4-bit decoding data. Loading port of check data and offset data (K3BC~E) are common and selection of loading is SIO2 data Select bit (L3B8). If the bit is set to "0", the offset data will be loaded and set to "1", the check data will be loaded. If the data "1" is set to SIOon bit (L22) and SIO Select bit (L23), SIO2 will be in a permission state of operation. If the data "1" is set to STA bit (L23), 26-bit shift registers are all reset and SI terminal input state will be serially input one by one by the shift register with the shift clock of SCK terminal clock. If SIO interruption is permitted at this time, interruption will be published with edge contrary to the shift edge of a shift clock. SI terminal and SO terminal can be changed to a serial input terminal by the SO-I/O bit, if the data "0" is set up, SI terminal will serve as a serial data and "1" will be set up, SO terminal will serve as a serial data input. If SI terminal is selected as a serial input, since SO terminal turns into a SIO1 serial output terminal, we recommend use of SO terminal to a serial input. These data is divided and indirect specified set up by the data select port (L2D). The data of a specification port to set DAL address port to beforehand is set, and the data port corresponding to it is accessed. A data selection port is +1 increment by accessing of DAL address port (KL3B). For this reason, after setting up a data selection port, it can set up continuously.
Note: The data select port is +1 increment automatically by accessing L2E, L2F, L3B and K3B on I/O map.
Control and serial data of the serial interface-2 is accessed using an OUT2 instruction for which [CN = 3H] has been specified in the operand.

A/D converter is the serial comparison systems of 6 bit decomposition ability. An internal power supply (VDD) is used for the standard voltage of A/D conversion. The voltage dividing this power supply by 64 and the A/D input voltage are compared, and the data is output to the A/D conversion data port. The A/D conversion input follows the multiplex method for the four channels of the external input terminals (ADin1~ADin4 terminal) and the 1/2 potential of the Vreg terminal voltage, and is selected using bits AD SEL0 to AD SEL2. The A/D converter performs A/D conversion whenever the STA bit is set at "1", and this ends after seven machine cycles (280 s). The completion of A/D conversion is determined by reference to the BUSY bit, and the A/D conversion data is loaded into the data memory after conversion has finished. The result of A/D conversion is obtained through the following calculation. VDD x n - 0.5 64 (63 > n > 1) < A/D input voltage < VDD x == = = n + 0.5 64 (62 > n > 0) ==
(n is the A/D conversion data value. [decimal]) The Vreg/2 to the A/D input is used for battery detection. The Vreg potential is 1.5 V 0.15 V and 1/2 potential: 0.75 V 0.075 V of Vreg terminal voltage is chosen as A/D input, and VDD potential which is standard potential can be detected by carrying out A/D conversion of this potential. When VDD potential is 1.5 V, A/D conversion data is set to 20H, and if A/D data goes up and VDD potential serves as 0.75 V as VDD potential falls, it will serve as 3FH. If this function is used, the VregON bit is set to "1". These controls are accessed with an OUT2/IN2 instruction for which [CN = 0H, 1H] has been specified in the operand.
Note: If the VregON bit is set to "1" , the CPU operating consumption current is increased. The Vreg terminal also supplies power to the phase comparator.

Ports P4-0 I/O are also used for buzzer output. In order to set it as a buzzer output, BUZR ON bit is set up "1" and it changes to a buzzer output by setting it as an output by the P4-0 I/O control port. After logic setting up of buzzer frequency, mode setup and a logic setup, buzzer enable bit is set up "1", it outputs buzzer. At the time of condition setup, buzzer enable bit is setup "0". In continual output mode (mode A), if the buzzer enable bit is set to "1", the buzzer frequency will be output continuously; if "0" is set, the buzzer output will stop. In staggered output mode, whenever the buzzer enable bit is set to "1", the buzzer is output and stopped at 50-ms intervals. Under a buzzer output (50 ms), if buzzer enable bit is set to "1" again, the buzzer is extended to 50 ms, being output for 100 ms. Given that a further extension of 50 ms to 150 ms is possible, the buzzer time can be set up easily. In the 10-Hz intermittent output mode (mode C), if the buzzer enable bit is set to "1", a 50-ms buzzer output and 50-ms buzzer pause are carried out continuously. A setting of "0" stops the buzzer output.

A set of "0" stops a buzzer output. At mode B, C, and D, a buzzer is in an output state, even if it sets "0" to buzzer enable bit and it makes it stop, the buzzer of 50 ms is output and stops. In addition, a buzzer output state can be judged according to the contents of a timer port. The timer port 10 Hz bit is "0", buzzer is an output state and it is in a pause state at the time of "1".

The pulse counter measures the number of pulses in the PCTRin input terminal. POL bit set up the clock edge of input terminal. If "0" is set, it will count in the falling of an input and it will set to "1", it will count in the rising of an input. Usually, this bit is used fixed. DOWN bit sets up a up/down of 8-bit counter. If it sets to "0" and it will set to rise count operation and "1", down count operation will be done. A change of a rise/down can be performed freely. However, if a clock pulse is input during change command execution, since it is canceled, be careful of this count. When 28 or more pulses are input, OVER F/F bit is set to "1". When performing count operation of 8-bits or more, this OVER F/F are detected, and on a data memory, only the number of times of overflow is added and subtracted, and can correspond. After detection by this bit, and OVER RESET bit is set "1" and OVER F/F is reset. The CTR RESET bit resets only the 8-bit counter. The counter is reset whenever this bit is set to "1". Counter data loaded data in a data memory by the binary. The control of pulse counter and data loading is accessed using the OUT3/IN3 instructions for which [CN = BH] have been specified in the operand and arranges in DAL address register port. This port is set up by data select port (L2D), which specified the division. The data of a specification port to set beforehand is set and the data port corresponding to it can be accessed. The data select port is +1 increments whenever it accesses DAL address port (L3B, K3B). For this reason, after setting up a data selection port, it can set up continuously.
Note: If POL bit is changed, a clock pulse may enter. Reset data by the reset bit after changing. Note: If data select port is +1 increments whenever it accesses L2E, L2F, L3B, K3B on the I/O map.

The I/O port for the I/O ports is set with the contents of the I/O control data port. "0" is set in the I/O control data port bit which corresponds to the relevant port when setting the input port, and "1" is set when setting the output port. I/O control data port is arranged segment-2 data port and set up by data select port (L2D), which specified the division. The data of a specification port to set beforehand is set and the data port corresponding to it can be accessed. The data select port is +1 increments whenever it accesses DAL address port (L2F). For this reason, after setting up a data selection port, it can set up continuously. The output status of the I/O port is controlled by executing the OUT3 instruction for which corresponds to each I/O port during output port setting. The contents of the data currently output can also be loaded into the data memory by executing the IN3 instruction. In addition, the data read by the IN3 command is not surely in agreement with the data output by the OUT3 instruction and, in order to read the state of a terminal. The data input in the I/O port is loaded into the data memory by executing the IN3 instruction which corresponds to each I/O port during input port setting. The contents of the output latch will have absolutely no effect on the input data at this point. Nch open drain I/O ports have not I/O control data. When it makes an input, it is set "1" in I/O data port, the status becomes high impedance and read the input status into data memory by IN3 instruction. When output state becomes "L" level, it set "0" in I/O data port by OUT3 command. The execution of the WAIT instruction and CKSTP instruction is cancelled and CPU operations are re-started when the status of the I/O port input specified in the input port changes with I/O port-1. Also, the MUTE port and MUTE bit are forcibly set to "1" during changes in the input status when the MUTE port's I/O bit is set at "1". By control port of I/O port-1 pull-down, it sets up pull-down or pull-up status. It can set up a pull-down or pull-up for every terminal and if the port is set up "1", it will become a pull-up or a pull-down. The pull-up/pull down control bit of I/O Port -1 perform a change of a pull-up and a pull down. The status is pull-down if the bit is set to "0", and pull-up if the bit is set to "1"

Set up the pull-up and pull-down is used for key matrix configuration. I/O Port -1 with a pull down or a pull-up is considered for a usual I/O Port output as an input as an output of a key matrix, and a key matrix is constituted. It is able to constitute of the key matrix of a low noise by the following methods. In setting pull-down to I/O port-1, the output side of a key matrix is usually high impedance (input state), output and scan to "H" level on key loaded line, detected key input or non by loading input status of I/O port-1. In the case of a pull-up, "L" level is output and it detected on a key loading line. During executing of CKSTP instruction and WAIT instruction, the existence of this key input can also be judged and re-started. When re-starting at the time of CKSTP command execution, I/O Port -1 is used by changing into a pull-up state. For the clock stop mode, since the outputs of an I/O Port are output all "L" level, I/O Port -1 stands by in the state of a pull-up, and if a key is input, I/O Port -1 input will change and re-start. In this case, since the standby time of about 100 ms occurs as time lag after being canceled of a clock stop. Since release of WAIT instruction holds the output state, re-starting is possible by the method of both a pull-up and a pull down, and since there is no time lag from release, detection and operation of a key are quickly possible. Using these backup modes together can reduce consumption current. Since the input of I/O Port -1 is an inverter input, the usage that serves as middle potential cannot be done to this input. But, only at the time of execution of the input instruction, since an input will be in an ON state, even if middle potential is input, as for other I/O Port inputs, unusual consumption current does not occur. For this reason, use of the pull-up in potential lower than VDD potential, the three value output of an output level, etc. is possible. I/O Port -2, -4 terminals are the I/O Ports of CMOS structure, P2-3 terminal is the prescaler PSC output, P4-0 terminal is the buzzer output and P3-1-3 terminals are the serial interface serve a double purpose, respectively. I/O port-3, -5, -8~-9 are Nch open drain I/O port. I/O Port -3 uses VLCD (3 V) for the gate potential of Nch output buffer. For this reason, the output current by which power supply voltage was stabilized also in the time of low voltage can be obtained. This port can perform the input and output to 3.6 V. I/O port-5 is used as 6-bit A/D converter input. This port is able to input VDB potential (the potential to VDD x 2). I/O Port -8, -9 are using also LCD driver. VLCD (3 V) is used for the gate potential of an Nch open output buffer. For this reason, the output current by which power supply voltage was stabilized also in the time of low voltage can be obtained. These terminals can perform the input and output to VLCD (3 V). These terminals are set as the input of an I/O Port after reset.
Note: The data select port is +1 increments automatically when it accesses L2E, L2F, L3B, K3B on the I/Omap.
The following is an example of key input matrix circuit configuration. Without key input, it pulled-up and key is pushed, it input "L" level from souce side(I/O port-9). It is necessary to take into consideration the shift time to the pull-up of a key input from "L". They are all about a key souce side at the time of WAIT instruction execution and "L" WAIT instruction can be lifted, whenever a key input will be pushed, if it stands by on the level.

Register Port
The G-register and data register outlined in the explanation on the CPU are also used as a single internal port.
1. G-register (KL1D, KL1E)
This register addresses the data memory's row addresses (DR = 04H~3FH) during execution of the MVGD instruction and MVGS instruction. The register is accessed using an OUT1/IN1 instruction for which [CN = DH~EH] has been specified in the operand. Moreover, if STGI instruction is used, data can be set to this register using a single instruction.
Note: The contents of this register are only valid when the MVGD instruction and MVGS instruction are executed and are ineffective when any other instruciton is executed. Moreover, this register is not affected by MVGD instruction and MVGS instruction. Note: All of the data memory row addresses can be specified indirectly by setting data 00H to 3FH in the G-register. (DR = 00H~3FH) Note: For a reason with a RAM capacity of 256 words, this product will become unfixed if 10H-3FH is specified to be G-register. Note: Writing and read-out are possible for this register. Please evacuate and return in a data memory if needed at the time of interruption.

The data register is 16-bit register for which load the program memory data when the DAL instruction is executed. The contents of this register are loaded into the data memory in 4-bit units with the execution of the OUT1/IN1 instructions for which [CN = CH~FH] has been specified in the operand. This register can be used for loading LCD segment decoding operations, radio band edge data and the data related to binary to BCD conversion. The DAL address register (DA) is 14-bit register for which specified the program memory indirectly when the DAL instruction is executed. There are 2 kinds of operation methods of DAL instruction. The control is selected by DAL bit. When DAL bit is set "0", ADDR3 (6 bit) of the operand and contents of general register (r) becomes the reference address of program memory and when DAL bit is set "1", 14 bit of DAL address register becomes reference address. At the time of setting DAL bit is "0" and execution of DAL instruction, only program memory area (0000H~03FFH) becomes reference area and DAL bit is set "1" and execution of DAL instruction, all program memory area (0000H~3FFFH) becomes reference area. If (DATA) DA bit is set to "1", it can transfer from the contents of data register to 14 bit DAL address register by executing of single instruction. The contents of DAL address register are accessed the data in 4-bit units with the execution of the OUT3/IN3 instruction for which [CN = BH] have been specified in the operand. DAL address register port is setup by data select port (L2D) for which divides and indirect specified. The data of a specification port to set beforehand is set and the data port corresponding to it is accessed. Data select port is +1 incremented whenever is accessed this port(L3B, K3B). For this reason, after setting up a data selection port, it can access continuously. DAL bit and (DATA) DA bit are accessed with the execution of OUT3/IN3 instruction for which [CN = AH] has been specified in the operand.
Note: DAL address register becomes effective only execution of DAL instruction when setting "1" and becomes unrelated at the time of other instruction execution. It does not have the influence on this register by DAL instruction. Note: For this product have 4 k step of ROM Capacity, If 1000H - 3FFFH is specified to be DAL address register and DAL instructiion is executed, the contents of a data register will become unfixed. Note: It's possible to write in and read out for data register and DAL address register. Please evacuate and return in a data memory if needed at the time of interruption. Note: It's no action when (DATA) DA bit is set "0" . When it accesses to K3A, it only read out only the DAL bit. (The other bit is "0".)
3. Carry F/F (Ca flag, KL1C)
This is set when either Carry or Borrow are issued in the result of calculation instruction execution and is reset if neither of these is issued. The carry F/F is accessed with OUT1/IN1 instructions for which [CN = CH] have been specified. For this reason, evacuation and a return of the carry F/F at the time of interruption can be performed easily. Carry F/F is written in a data memory by IN1 instruction at the time of evacuation, it is evacuated, and the data evacuated by OUT1 instruction is transmitted to carry F/F from a data memory at the time of a return.

Output Port (Both as LCD Driver Terminal)
There are 14-output ports of 14 CMOS type. These output ports are used as LCD driver and changed output port by VLCD OFF bit. If VLCD OFF bit is set to "1", this port becomes output port. The output data to output port is used as segment data port-1 (L2E). This data is accessed with OUT2 instruction for which [CN = EH] is specified and is setup by data select port (L2D) for which divides and indirect specified as same as segment data. The data of a specification port to set a segment data port to beforehand is set, and the data port corresponding to it is accessed. The data select port is +1 incremented whenever is accessed segment data port-1 (L2E). For this reason, after setting up a data selection port, it can set up continuously. Output data is +1 increment with OT count UP bit by executing one instruction. For this reason, it can be used as an address signal output when using an external memory etc. Output buffer capability can be changed at the time of an output setup. If OTB-UP bit is set "0", it becomes low output buffer (same performance of LCD output driver) and set "1", it becomes high output buffer. During output port setup, this bit is usually set to "1". The power supply of this output port is used VLCD doubler potential, when using it as an output port, remove for the capacitor of VLCD doubler potential (between C3-C4) and connect with VDD terminal and use VLCD terminal.
Note: Data select port is +1 increment automatically whenever is accessed L2E, L2F, L3B, K3B on I/O map. Note: If set "0" to OT count UP bit, it's not performed count-up. Note: Refer to LCD driver item.
