rev.6.00 jun. 03, 2008 page iii of xlviii rej09b0074-0600 general precautions in the handling of mpu/mcu products the following usage notes are applicable to all mpu/mcu products from renesas. for detailed usage notes on the products covered by this manual, refer to the relevant sections of the manual. if the descriptions under general precautions in the handling of mpu/mcu products and in the body of the manual differ from each other, the description in the body of the manual takes precedence. 1. handling of unused pins handle unused pins in accord with the directions given under handling of unused pins in the manual. ? the input pins of cmos products are generally in the high-impedance state. in operation with an unused pin in the open-circuit state, extra electromagnetic noise is induced in the vicinity of lsi, an associated shoot-through current flows internally, and malfunctions may occur due to the false recognition of the pin state as an input signal. unused pins should be handled as described under handling of unused pins in the manual. 2. processing at power-on the state of the product is undefined at the moment when power is supplied. ? the states of internal circuits in the lsi are indeterminate and the states of register settings and pins are undefined at the moment when power is supplied. in a finished product where the reset signal is applied to the external reset pin, the states of pins are not guaranteed from the moment when power is supplied until the reset process is completed. in a similar way, the states of pins in a product that is reset by an on-chip power-on reset function are not guaranteed from the moment when power is supplied until the power reaches the level at which resetting has been specified. 3. prohibition of access to reserved addresses access to reserved addresses is prohibited. ? the reserved addresses are provided for the possible future expansion of functions. do not access these addresses; the correct operation of lsi is not guaranteed if they are accessed. 4. clock signals after applying a reset, only release the reset line after the operating clock signal has become stable. when switching the clock signal during program execution, wait until the target clock signal has stabilized. ? when the clock signal is generated with an external resonator (or from an external oscillator) during a reset, ensure that the reset line is only released after full stabilization of the clock signal. moreover, when switching to a clock signal produced with an external resonator (or by an external oscillator) while program execution is in progress, wait until the target clock signal is stable. 5. differences between products before changing from one product to another, i.e. to one with a different type number, confirm that the change will not lead to problems. ? the characteristics of mpu/mcu in the same group but having different type numbers may differ because of the differences in internal memory capacity and layout pattern. when changing to products of different type numbers, implement a system-evaluation test for each of the products.

rev.6.00 jun. 03, 2008 page ix of xlviii rej09b0074-0600 item page revision (see manual for details) 12.7.7 serial data transmission (except for block transfer mode) 432 description amended and added figure 12.31 shows a flowchart for transmission. a sequence of transmit operations can be performed automatically by specifying the dmac to be activated with a txi interrupt source. in a transmit operation, the tdre flag is set to 1 at the same time as the tend flag in ssr is set, and a txi interrupt will be generated if the tie bit in scr has been set to 1. if the txi request is designated beforehand as a dmac activation source, the dmac will be activated by the txi request, and transfer of the transmit data will be carried out. the tdre and tend flags are automatically cleared to 0 when data is transferred by the dmac. in the event of an error, the sci retransmits the same data automatically. during this period, the tend flag remains cleared to 0 and the dmac is not activated. therefore, the sci and dmac will automatically transmit the specified number of bytes in the event of an error, including retransmission. however, the ers flag is not cleared automatically when an error occurs, and so the rie bit should be set to 1 beforehand so that an eri request will be generated in the event of an error, and the ers flag will be cleared. when using the dmac for data transmission or reception, always make dmac settings and enable the dmac before making sci settings. for details on dmac settings, see section 7, dma controller (dmac). 12.7.8 serial data reception (except for block transfer mode) 435 description amended figure 12.33 shows a flowchart for reception. a sequence of receive operations can be performed automatically by specifying the dmac to be activated using an rxi interrupt source. in a receive operation, an rxi interrupt request is generated when the rdrf flag in ssr is set to 1. if the rxi request is designated beforehand as a dmac activation source, the dmac will be activated by the rxi request, and the receive data will be transferred. the rdrf flag is cleared to 0 automatically when data is transferred by the dmac. if an error occurs in receive mode and the orer or per flag is set to 1, a transfer error interrupt (eri) request will be generated. hence, so the error flag must be cleared to 0. in the event of an error, the dmac is not activated and receive data is skipped. therefore, receive data is transferred for only the specified number of bytes in the event of an error. even when a parity error occurs in receive mode and the per flag is set to 1, the data that has been received is transferred to rdr and can be read from there.

(when an instruction is fetched, the least significant pc bit is regarded as 0.) 2.4.3 extended control register (exr) exr is an 8-bit register that manipulates the ldc, stc, andc, orc, and xorc instructions. when these instructions except for the stc instruction is executed, all interrupts including nmi will be masked for three states after execution is completed. bit bit name initial value r/w description 7 t 0 r/w trace bit when this bit is set to 1, a trace exception is generated each time an instruction is executed. when this bit is cleared to 0, instructions are executed in sequence. 6 to 3 ? all 1 ? reserved these bits are always read as 1. 2 1 0 i2 i1 i0 1 r/w these bits designate the interrupt mask level (0 to 7). for details, refer to section 5, interrupt controller.
section 2 cpu rev.6.00 jun. 03, 2008 page 42 of 698 rej09b0074-0600 2.4.4 condition-code register (ccr) this 8-bit register contains internal cpu status information, including an interrupt mask bit (i) and half-carry (h), negative (n), zero (z), overflow (v), and carry (c) flags. operations can be performed on the ccr bits by the ldc, stc, andc, orc, and xorc instructions. the n, z, v, and c flags are used as branching conditions for conditional branch (bcc) instructions. bit bit name initial value r/w description 7 i 1 r/w interrupt mask bit masks interrupts other than nmi when set to 1. nmi is accepted regardless of the i bit setting. the i bit is set to 1 by hardware at the start of an exception-handling sequence. for details, refer to section 5, interrupt controller. 6 ui undefined r/w user bit or interrupt mask bit can be written and read by software using the ldc, stc, andc, orc, and xorc instructions. this bit cannot be used as an interrupt mask bit in this lsi. 5 h undefined r/w half-carry flag when the add.b, addx.b, sub.b, subx.b, cmp.b or neg.b instruction is executed, this flag is set to 1 if there is a carry or borrow at bit 3, and cleared to 0 otherwise. when the add.w, sub.w, cmp.w, or neg.w instruction is executed, the h flag is set to 1 if there is a carry or borrow at bit 11, and cleared to 0 otherwise. when the add.l, sub.l, cmp.l, or neg.l instruction is executed, the h flag is set to 1 if there is a carry or borrow at bit 27, and cleared to 0 otherwise. 4 u undefined r/w user bit can be written and read by software using the ldc, stc, andc, orc, and xorc instructions. 3 n undefined r/w negative flag stores the value of the most significant bit of data as a sign bit. 2 z undefined r/w zero flag set to 1 to indicate zero data, and cleared to 0 to indicate non-zero data.

section 2 cpu rev.6.00 jun. 03, 2008 page 66 of 698 rej09b0074-0600 2.9 usage notes 2.9.1 note on tas instruction usage only register er0, er1, er4, or er5 should be used when using the tas instruction. the tas instruction is not generated by the renesas technology h8s and h8/300 series c/c++ compilers. if the tas instruction is used as a user-defined intrinsic function, ensure that only register er0, er1, er4, or er5 is used. 2.9.2 stm/ltm instruction usage with the stm or ldm instruction, the er7 register is used as the stack pointer, and thus cannot be used as a register that allows save (stm) or restore (ldm) operation. with a single stm or ldm instruction, two to four registers can be saved or restored. the available registers are as follows: for two registers: er0 and er1, er2 and er3, or er4 and er5 for three registers: er0 to er2, or er4 to er6 for four registers: er0 to er3 for the renesas technology h8s or h8/300 series c/c++ compiler, the stm/ldm instruction including er7 is not created. 2.9.3 note on bit manipulation instructions using bit manipulation instructions on registers containing write-only bits can result in the bits that should have been manipulated not being manipulated as intended or in the wrong bits being manipulated. reading data from a register containing write-only bits may return fixed or undefined values. consequently, bit manipulation instructions that use the read values to perform operations (bnot, btst, band, biand, bor, bior, bxor, bixor, bld, and bild) will not work properly. in addition, bit manipulation instructions that write data following operations based on the data values read (bset, bclr, bnot, bst, and bist) may change the values of bits unrelated to the intended bit manipulation. therefore, cautio n is necessary when using bit manipulation instructions on registers containing write-only bits.
section 2 cpu rev.6.00 jun. 03, 2008 page 67 of 698 rej09b0074-0600 the instructions bset, bclr, bnot, bst, and bist perform the following operations in the order shown: 1. read data in byte units 2. perform bit manipulation on the r ead data according to the instruction 3. write data in byte units example: using the bclr instruction to clear pin 14 only of p1ddr for port 1 p1ddr is an 8-bit register that contains write-only bits. it is used to specify the i/o setting of the individual pins in port 1. reading produces invalid data. attempting to read from p1ddr returns undefined values. in this example, the bclr instruction is used to set pin 14 as an input port. let us assume that pins 17 to 14 are presently set as output pins and pins 13 to 10 are set as input pins. thus, the value of p1ddr is initially h'f0. p17 p16 p15 p14 p13 p12 p11 p10 i/o output output output output input input input input p1ddr 1 1 1 1 0 0 0 0 to change pin 14 from an output pin to an input pin, the value of bit 4 in p1ddr must be changed from 1 to 0 (h'f0 to h'e0). now assume that the bclr instruction is used to clear bit 4 in p1ddr to 0. bclr #4, @p1ddr however, using the above bit manipulation instruction on the write-only register p1ddr can cause problems, as described below. the bclr instruction first reads data from p1ddr in byte units, but in this case the read values are undefined. these undefined values can be 0 or 1 for each bit in the register, but there is no way of telling which. since all of the bits in p1ddr are write-only, undefined values are returned for all of the bits when the register is read. in this example the value of p1ddr is h'f0, but we will assume that the value returned when the register was read is h'f8, which would give bit 3 a value of 1.
section 2 cpu rev.6.00 jun. 03, 2008 page 68 of 698 rej09b0074-0600 p17 p16 p15 p14 p13 p12 p11 p10 i/o output output output output input input input input p1ddr 1 1 1 1 0 0 0 0 read value 1 1 1 1 1 0 0 0 the bclr instruction performs bit manipulation on the read value, which is h'f8 in this example. it clears bit 4 to 0. p17 p16 p15 p14 p13 p12 p11 p10 i/o output output output output input input input input p1ddr 1 1 1 1 0 0 0 0 after bit manipulation 1 1 1 0 1 0 0 0 following bit manipulation the data is written to p1ddr and the bclr instruction terminates. p17 p16 p15 p14 p13 p12 p11 p10 i/o output output output input output input input input p1ddr 1 1 1 0 1 0 0 0 write value 1 1 1 0 1 0 0 0 the contents of p1ddr should have been overwritten with a value of h'e0, but in fact a value of h'e8 was written to the register. this changed pin 13, which should have been an input pin, to an output pin. in this example we assumed that the value of bit 1 in p1ddr was 1. however, since the values of bits 7 to 0 in p1ddr are all undefined when read, there is the possibility that individual bit values could be changed from 0 to 1 or from 1 to 0. to prevent this from happening, the recommendations in section 2.9.4, accessing registers containing write-only bits, should be followed when changing the values of registers containing write-only bits. in addition, the bclr instruction can be used to clear flags in internal i/o registers to 0. in such cases it is not necessary to read the relevant flag beforehand so long as it is clear that it has been set to 1 by an interrupt processing routine or the like. 2.9.4 accessing registers containing write-only bits using data transfer instructions or bit manipulation instructions on registers containing write-only bits can result in undefined values being read. to prevent the reading of undefined values, the procedure described below should be used to access registers containing write-only bits.
section 2 cpu rev.6.00 jun. 03, 2008 page 69 of 698 rej09b0074-0600 in order to write to a register containing write-only bits, set aside a work area in memory (in on- chip ram, for example) and write the data to be manipulated to it. after accessing and manipulating the data in the work area in memory, write the resulting data to the register containing write-only bits. figure 2.14 example flowchart of method for accessing registers containing write-only bits write data to work area write data from work area to register containing write-only bits access data in work area (using either data transfer instructions or bit manipulation instructions) write data from work area to register containing write-only bits write initial value change value of register containing write-only bits figure 2.14 flowchart of method for accessing registers containing write-only bits example: clearing pin 14 only of p1ddr for port 1 p1ddr is an 8-bit register that contains write-only bits. it is used to specify the i/o setting of the individual pins in port 1. reading produces invalid data. attempting to read from p1ddr returns undefined values. in this example, the bclr instruction is used to set pin 14 as an input port. to start, the initial value h'f0 to be written to p1ddr is written ahead of time to the work area (ram0) in memory. mov.b #h'f0, r0l mov.b r0l, @ram0 mov.b r0l, @p1ddr

section 4 exception handling rev.6.00 jun. 03, 2008 page 87 of 698 rej09b0074-0600 4.4 traces traces are enabled in interrupt control mode 2. trace mode is not activated in interrupt control mode 0, irrespective of the state of the t bit. for details of interrupt control modes, see section 5, interrupt controller. if the t bit in exr is set to 1, trace mode is activated. in trace mode, a trace exception occurs on completion of each instruction. trace mode is not affected by interrupt masking. table 4.4 shows the state of ccr and exr after execution of trace exception handling. trace mode is canceled by clearing the t bit in exr to 0. the t bit saved on the stack retains its value of 1, and when control is returned from the trace exception handling routine by the rte instruction, trace mode resumes. trace exception handling is not carried out after execution of the rte instruction. interrupts are accepted even within the trace exception handling routine. table 4.4 status of ccr and exr after trace exception handling ccr exr interrupt control mode i ui i2 to i0 t 0 trace exception handling cannot be used. 2 1 ? ? 0 legend: 1: set to 1 0: cleared to 0 ?: retains value prior to execution. 4.5 interrupts interrupts are controlled by the interrupt controller. the interrupt controller has two interrupt control modes and can assign interrupts other than nmi to eight priority/mask levels to enable multiplexed interrupt control. the source to start interrupt exception handling and the vector address differ depending on the product. for details, refer to section 5, interrupt controller. the interrupt exception handling is as follows: 1. the values in the program counter (pc), condition code register (ccr), and extended control register (exr) are saved in the stack. 2. the interrupt mask bit is updated and the t bit is cleared. 3. a vector address corresponding to the interrupt source is generated, the start address is loaded from the vector table to the pc, and program execution starts from that address.
section 4 exception handling rev.6.00 jun. 03, 2008 page 88 of 698 rej09b0074-0600 4.6 trap instruction trap instruction exception handling starts when a trapa instruction is executed. trap instruction exception handling can be executed at all times in the program execution state. the trap instruction exception handling is as follows: 1. the values in the program counter (pc), condition code register (ccr), and extended control register (exr) are saved in the stack. 2. the interrupt mask bit is updated and the t bit is cleared. 3. a vector address corresponding to the interrupt source is generated, the start address is loaded from the vector table to the pc, and program execution starts from that address. the trapa instruction fetches a start address from a vector table entry corresponding to a vector number from 0 to 3, as specified in the instruction code. table 4.5 shows the status of ccr and exr after execution of trap instruction exception handling. table 4.5 status of ccr and exr after trap instruction exception handling ccr exr interrupt control mode i ui i2 to i0 t 0 1 ? ? ? 2 1 ? ? 0 legend: 1: set to 1 0: cleared to 0 ?: retains value prior to execution.

section 5 interrupt controller rev.6.00 jun. 03, 2008 page 113 of 698 rej09b0074-0600 5.7.2 instructions that disable interrupts instructions that disable interrupts are ldc, andc, orc, and xorc. after any of these instructions is executed, all interrupts including nmi are disabled and the next instruction is always executed. when the i bit is set by one of these instructions, the new value becomes valid two states after execution of the instruction ends. 5.7.3 times when interrupts are disabled there are times when interrupt acceptance is disabled by the interrupt controller. the interrupt controller disables interrupt accep tance for a 3-state period after the cpu has updated the mask level with an ldc, andc, orc, or xorc instruction. 5.7.4 interrupts during execution of eepmov instruction interrupt operation differs between the eepmov.b instruction and the eepmov.w instruction. with the eepmov.b instruction, an interrupt request (including nmi) issued during the transfer is not accepted until the move is completed. with the eepmov.w instruction, if an interrupt request is issued during the transfer, interrupt exception handling starts at a break in the transfer cycle. the pc value saved on the stack in this case is the address of the next instruction. therefore, if an interrupt is generated during execution of an eepmov.w instruction, the following coding should be used. l1: eepmov.w mov.w r4, r4 bne l1 5.7.5 irq interrupt when operating by clock input, acceptance of input to an irq is synchronized with the clock. in software standby mode and watch mode, the input is accepted asynchronously. for details on the input conditions, see section 22.4.2, control signal timing.

section 6 bus controller rev.6.00 jun. 03, 2008 page 149 of 698 rej09b0074-0600 6.7.2 wait control as with the basic bus interface, either program wait insertion or pin wait insertion using the wait pin can be used in the initial cycle (full access) of the burst rom interface. see section 6.6.4, wait control. wait states cannot be inserted in a burst cycle. 6.8 idle cycle when the h8s/2218 group accesses external space, it can insert a 1-state idle cycle (t i ) between bus cycles in the following two cases: (1) wh en read accesses between different areas occur consecutively, and (2) when a write cycle occurs im mediately after a read cycle. by inserting an idle cycle it is possible, for example, to avoid data collisions between rom, with a long output floating time, and high-speed memory, i/o interfaces, and so on. consecutive reads betw een different areas: if consecutive reads between different areas occur while the icis1 bit in bcrh is set to 1, an idle cy cle is inserted at the start of the second read cycle. figure 6.22 shows an example of the operation in this case. in this example, bus cycle a is a read cycle from rom with a long output floating time, and bus cycle b is a read cycle from sram, each being located in a different area. in (a), an idle cycle is not inserted, and a collision occurs in cycle b between the read data from rom and that from sram. in (b), an idle cycle is inserted, and a data collision is prevented.

section 6 bus controller rev.6.00 jun. 03, 2008 page 153 of 698 rej09b0074-0600 6.9 bus release the h8s/2218 group can release the external bus in response to a bus request from an external device. in the external bus released state, the internal bus master continues to operate as long as there is no external access. in external extended mode, the bus can be released to an external device by setting the brle bit in bcrl to 1. driving the breq pin low issues an external bus request to this lsi. when the breq pin is sampled, at the prescribed timing the back pin is driven low, and the address bus, data bus, and bus control signals are placed in the high-impedance state, establishing the external bus- released state. in the external bus released state, an internal bus master can perform accesses using the internal bus. when an internal bus master wants to make an external access, it temporarily defers activation of the bus cycle, and waits for the bus request from the external bus master to be dropped. when the breq pin is driven high, the back pin is driven high at the prescribed timing and the external bus released state is terminated. in the event of simultaneous external bus release request and external access request generation, the order of priority is as follows: (high) external bus release > intern al bus master external access (low) table 6.5 shows pin states in the external bus released state. in the h8s/2212 group, the brle bit in bcrl should not be set to 1. table 6.5 pin states in bus released state pins pin state a23 to a0 high impedance d15 to d0 high impedance csn high impedance as high impedance rd high impedance hwr high impedance lwr high impedance

section 6 bus controller rev.6.00 jun. 03, 2008 page 155 of 698 rej09b0074-0600 6.10 bus arbitration this lsi has a bus arbiter that arbitrates bus master operations. there are two bus masters, the cpu and dmac, which perform read/write operations when they have possession of the bus. each bus master requests the bus by means of a bus request signal. the bus arbiter determines priorities at the prescribed timing, and permits use of the bus by means of a bus request acknowledge signal. the selected bus master then takes possession of the bus and begins its operation. 6.10.1 operation the bus arbiter detects the bus masters' bus request signals, and if the bus is requested, sends a bus request acknowledge signal to the bus master making the request. if there are bus requests from more than one bus master, the bus request acknowledge signal is sent to the one with the highest priority. when a bus master receives the bus request acknowledge signal, it takes possession of the bus until that signal is canceled. the order of priority of the bus masters is as follows: (high) dmac > cpu (low) an internal bus access by an internal bus master, and external bus release, can be executed in parallel in the h8s/2218 group. in the event of simultaneous external bus release request, and internal bus master external access request generation, the order of priority is as follows: (high) external bus release > intern al bus master external access (low) the h8s/2212 group does not have the external bus release function. 6.10.2 bus transfer timing even if a bus request is received from a bus master with a higher priority than that of the bus master that has acquired the bus and is currently operating, the bus is not necessarily transferred immediately. there are specific times at which each bus master can relinquish the bus. cpu: the cpu is the lowest-priority bus master, and if a bus request is received from the dmac, the bus arbiter transfers the bus to the bus master th at issued the request. the timing for transfer of the bus is as follows:
section 6 bus controller rev.6.00 jun. 03, 2008 page 156 of 698 rej09b0074-0600 ? the bus is transferred at a break between bus cycles. however, if a bus cycle is executed in discrete operations, as in the case of a longword-size access, the bus is not transferred between the operations. ? if the cpu is in sleep mode, it transfers the bus immediately. dmac: the dmac sends the bus arbiter a request for the bus when an activation request is generated. in the case of a usb request in short address mode or normal mode, and in cycle steal mode, the dmac releases the bus after a single transfer. in block transfer mode, it releases the bus after transfer of one block, and in burst mode, after completion of the transfer. 6.10.3 external bus release usage note external bus release can be performed on completion of an external bus cycle in the h8s/2218 group. the cs signal remains low until the end of the external bus cycle. therefore, when external bus release is performed, the cs signal may change from the low level to the high- impedance state. 6.11 resets and the bus controller in a power-on reset, this lsi, including the bus cont roller, enters the reset state at that point, and an executing bus cycle is discontinued. in a manual reset*, the bus controller's registers and internal state are maintained, and an executing external bus cycle is completed. in this case, wait input is ignored and write data is not guaranteed. note: * supported only by the h8s/2218 group.

(b) etcrb etcrb is not used in normal mode. ? block transfer mode (a) etcra in block transfer mode, etcral functions as an 8-bit block size counter and etcrah holds the block size. etcral is decremented each time a 1-byte or 1-word transfer is performed, and when the count reaches h'00, etcral is loaded with the value in etcrah. so by setting the block size in etcrah and etcral, it is possible to repeatedly transfer blocks consisting of any desired number of bytes or words. (b) etcrb etcrb functions in block transfer mode, as a 16-bit block transfer counter. etcrb is decremented by 1 each time a block is transferred, and transfer ends when the count reaches h'0000.

(2) bus interface the bus interface of the module conforms to the bus specifications for external area 7. consequently, before accessing the rtc module, area 7 must be specified as having an 8-bit bus width and 3-state access using the bus controller register. (3) method for reading pin states using the port d register (portd) first access exmdlstp or the rtc register (address range: h'ffff40 to h'ffff5f). then, you must perform a dummy read to the external address space (such as h'ffef00 to h'ff7ff) outside the range h'ffff40 to h'ffff5f before reading portd.
section 12 serial communication interface rev.6.00 jun. 03, 2008 page 363 of 698 rej09b0074-0600 section 12 serial communication interface this lsi has two independent serial communication interface (sci) channels. the sci can handle both asynchronous and clocked synchronous serial communication. asynchronous serial data communication can be carried out using standard asynchronous communication chips such as a universal asynchronous receiver/transmitter (uart) or an asynchronous communication interface adapter (acia). a function is also provided for serial communication between processors (multiprocessor communication functio n). the sci also supports the smart card (ic card) interface based on iso/iec 7816-3 (identification card) as an enhanced asynchronous communication function. 12.1 features ? choice of asynchronous or clocked synchronous serial communication mode ? full-duplex communication capability the transmitter and receiver are mutually indepe ndent, enabling transmis sion and reception to be executed simultaneously. double-buffering is used in both the transm itter and the receiver, enabling continuous transmission and continuous reception of serial data. on-chip baud rate generator allows any bit rate to be selected external clock can be selected as a transfer clock source (except for in smart card interface mode). ? choice of lsb-first or msb-first transfer (except in the case of asynchronous mode 7-bit data) ? four interrupt sources transmit-end, transmit-data-empty, receive-data-full, and receive error ? that can issue requests. the transmit-data-empty interrupt and receive data full interrupts can be used to activate the direct memory access controller (dmac). ? module stop mode can be set asynchronous mode ? data length: 7 or 8 bits ? stop bit length: 1 or 2 bits ? parity: even, odd, or none ? receive error detection: parity, overrun, and framing errors ? break detection: break can be detected by read ing the rxd pin level directly in the case of a framing error

(l ? 0.5) f ? (1+ f) | 100 [%] ... formula (1) 2n 1 n | d ? 0.5 | where m: reception margin n: ratio of bit rate to clock (n = 16 if abcs = 0, n = 8 if abcs = 1) d: clock duty (d = 0 to 1.0) l: frame length (l = 9 to 12) f: absolute value of clock rate deviation assuming values of f (absolute value of clock rate deviation) = 0, d (clock duty) = 0.5, and n (ratio of bit rate to clock) = 16 in formula (1), the reception margin can be given by the formula. m = {0.5 ? 1/(2 16)} 100 [%] = 46.875% however, this is only the computed value, and a margin of 20% to 30% should be allowed for in system design. internal basic clock 16 clocks * 8 clocks * receive data (rxd) synchronization sampling timing start bit d0 d1 data sampling timing 15 0 7 15 0 07 figure 12.6 receive data samplin g timing in asynchronous mode
section 12 serial communication interface rev.6.00 jun. 03, 2008 page 406 of 698 rej09b0074-0600 note: * figure 12.6 shows an example when the abcs bit of semra_0 is cleared to 0. when abcs is set to 1, the clock frequency of basic clock is 8 times the bit rate and the receive data is sampled at the rising ed ge of the 4th pulse of the basic clock. 12.4.3 clock either an internal clock generated by the on-chip ba ud rate generator or an external clock input at the sck pin can be selected as the sci's serial clock, according to the setting of the c/ a bit in smr and the cke0 and cke1 bits in scr. when an external clock is input at the sck pin, the clock frequency should be 16 times the bit rate used. when an external clock is selected, the basic clock of average transfer rate can be selected according to the acs2 to acs0 bit setting of semr_0. when the sci is operated on an internal clock, the clock can be output from the sck pin by setting cke1 = 0 and cke0 = 1. the frequency of th e clock output in this case is equal to the bit rate, and the phase is such that the rising edge of the clock is in the middle of the transmit data, as shown in figure 12.7. 0 1 frame d0 d1 d2 d3 d4 d5 d6 d7 0/1 11 sck txd figure 12.7 relationship between output clock and transfer data phase (asynchronous mode)

[4] 1-bit interval elapsed? [1] set the clock selection in scr. be sure to clear bits rie, tie, teie, and mpie, and bits te and re, to 0. when the clock is selected in asynchronous mode, it is output immediately after scr settings are made. [2] set the data transfer format in smr, scmr, and semra_0. [3] write a value corresponding to the bit rate to brr. not necessary if an external clock or average transfer rate clock by acs2 to acs0 is used. [4] wait at least one bit interval, then set the te bit or re bit in scr to 1. also set the rie, tie, teie, and mpie bits. setting the te and re bits enables use of the txd and rxd pins. figure 12.8 sample sci initialization flowchart
section 12 serial communication interface rev.6.00 jun. 03, 2008 page 408 of 698 rej09b0074-0600 12.4.5 data transmission (asynchronous mode) figure 12.9 shows an example of operation for transmission in asynchronous mode. in transmission, the sci operates as described below. 1. the sci monitors the tdre flag in ssr. if the flag is cleared to 0, the sci recognizes that data has been written to tdr, and transfers the data from tdr to tsr. 2. after transferring data from tdr to tsr, the sci sets the tdre flag to 1 and starts transmission. if the tie bit is set to 1 at this time, a transmit data empty interrupt request (txi) is generated. continuous transmission is possible because the txi interrupt routine writes next transmit data to tdr before transmission of the current transmit data has been completed. 3. data is sent from the txd pin in the following order: start bit, transmit data, parity bit or multiprocessor bit (may be omitted depending on the format), and stop bit. 4. the sci checks the tdre flag at the timing for sending the stop bit. 5. if the tdre flag is 0, the data is transferred from tdr to tsr, the stop bit is sent, and then serial transmission of the next frame is started. 6. if the tdre flag is 1, the tend flag in ssr is set to 1, the stop bit is sent, and then the "mark state" is entered, in which 1 is output. if the teie bit in scr is set to 1 at this time, a tei interrupt request is generated. tdre tend 0 1 frame d0 d1 d7 0/1 1 0 d0 d1 d7 0/1 1 1 1 data start bit parity bit stop bit start bit data parity bit stop bit txi interrupt request generated data written to tdr and tdre flag cleared to 0 in txi interrupt service routine tei interrupt request generated idle state (mark state) txi interrupt request generated figure 12.9 example of operation in transmission in asynchronous mode (example with 8-bit data, parity, one stop bit) figure 12.10 shows a sample flowchart for transmission in asynchronous mode.

[3] serial transmission continuation procedure: to continue serial transmission, read 1 from the tdre flag to confirm that writing is possible, then write data to tdr, and then clear the tdre flag to 0. checking and clearing of the tdre flag is automatic when the dmac is activated by a transmit data empty interrupt (txi) request, and data is written to tdr. [4] break output at the end of serial transmission: to output a break in serial transmission, set ddr for the port corresponding to the txd pin to 1, clear dr to 0, then clear the te bit in scr to 0. figure 12.10 sample serial data transmission flowchart

[1] sci initialization: the rxd pin is automatically designated as the receive data input pin. [2] [3] receive error processing and break detection: if a receive error occurs, read the orer, per, and fer flags in ssr to identify the error. after performing the appropriate error processing, ensure that the orer, per, and fer flags are all cleared to 0. reception cannot be resumed if any of these flags are set to 1. in the case of a framing error, a break can be detected by reading the value of the input port corresponding to the rxd pin. [4] sci status check and receive data read: read ssr and check that rdrf = 1, then read the receive data in rdr and clear the rdrf flag to 0. transition of the rdrf flag from 0 to 1 can also be identified by an rxi interrupt.

section 12 serial communication interface rev.6.00 jun. 03, 2008 page 421 of 698 rej09b0074-0600 12.6.3 serial data transmission (clocked synchronous mode) figure 12.19 shows an example of sci operation for transmission in clocked synchronous mode. in serial transmission, the sci operates as described below. 1. the sci monitors the tdre flag in ssr, and if the flag is 0, the sci recognizes that data has been written to tdr, and transfers the data from tdr to tsr. 2. after transferring data from tdr to tsr, the sci sets the tdre flag to 1 and starts transmission. if the tie bit in scr is set to 1 at this time, a transmit data empty interrupt (txi) is generated. continuous transmission is possible because the txi interrupt routine writes the next transmit data to tdr before transmission of the current transmit data has been completed. 3. 8-bit data is sent from the txd pin synchronized with the output clock when output clock mode has been specified, and synchronized with the input clock when use of an external clock has been specified. 4. the sci checks the tdre flag at the timing for sending the msb (bit 7). 5. if the tdre flag is cleared to 0, data is transferred from tdr to tsr, and serial transmission of the next frame is started. 6. if the tdre flag is set to 1, the tend flag in ssr is set to 1, and the tdre flag maintains the output state of the last bit. if the teie bit in s cr is set to 1 at this time, a tei interrupt request is generated. the sck pin is fixed high. figure 12.20 shows a sample flow chart for serial data transmission. even if the tdre flag is cleared to 0, transmission will not start while a recei ve error flag (orer, fer, or per) is set to 1. make sure that the receive error flags are cleared to 0 before starting transmission. note that clearing the re bit to 0 does not clear the receive error flags.

(in extest instruction, output parallel latches are always output to the output pins.) clamp: when the clamp instruction is selected output pins output the boundary scan register value which was specified by the sample/preload instruction in advance. while the clamp instruction is selected, the status of boundary scan register is maintained regardless of the tap controller state. bypass is connected between tdi and tdo, the same operation as bypass instruction can be achieved. highz: when the highz instruction is selected, all outputs enter high-impedance state. while this instruction is selected, the status of boundary scan register is maintained regardless of the tap controller state. bypass resistor is connected between tdi and tdo, the same operation as bypass instruction can be achieved. idcode: when the idcode instruction is selected, idcode register value is output to the tdo in shift-dr state of tap controller. in this case, idcode register value is output from the lsb. during this instruction execution, test circuit does not affect the system circuit. instr is initialized by the idcode instruction in test-logic-reset state of tap controller. bypass: the bypass instruction is a standard instruction necessary to operate bypass register. the bypass instruction improves the serial data transfer speed by bypassing the scan path. during this instruction execution, test circuit does not affect the system circuit.

(11 bits) fixed code (1 bit) 13.3.3 bypass register (bypass) bypass is a 1-bit register. if instr is specified to bypass mode, clamp mode, or highz mode, bypass is connected between tdi and tdo. 13.3.4 boundary scan register (bscanr) bscan is a 199-bit shift register assigned on the pins to control input/output pins. the i/o pins consists of three bits (in, control, out), input pins 1 bit (in), and output pins 1 bit (out) of shift registers. the boundary scan test based on the jtag standard can be performed by using instructions listed in table 13.2. table 13.4 shows the correspondence between the lsi pins and boundary scan registers. (in table 13.4, control indicates the high active pin. by specifying control to high, the pin is driven by out. ) figure 13.2 shows the boundary scan register configuration example.

section 14 universal serial bus (usb) rev.6.00 jun. 03, 2008 page 517 of 698 rej09b0074-0600 14.5.9 stall operations (1) overview this section describes stall operations in th e usb function module. there are two cases in which the usb function module stall function is used: . when the firmware forcibly stalls an endpoint for some reason . when a stall is performed automatically within the usb function module due to a usb specification violation. the usb function module has internal status bits that hold the status (stall or non-stall) of each endpoint. when a transaction is sent from the host, the module refers these internal status bits and determines whether to return a stall to the host. these bits cannot be cleared by the firmware; they must be cleared with a clear feature command from the host. however, the internal status bit for ep0 is cleared automatically at the reception of the setup command. (2) forcible stall by firmware the firmware uses the uestl register to issue a stall request for the usb function module. when the firmware wishes to stall a specific endpoint, it sets the corresponding epnstl bit (1- 1 in figure 14.20). the internal status bits are not changed at this time. when a transaction is sent from the host for the endpoint for which the epnstl bit was set, the usb function module refers the internal status bit, and if this is not set, refers the corresponding epnstl bit (1-2 in figure 14.20). if the corresponding epnstl bit is not set, the internal status bit is not changed and the transaction is accepted. if the corresponding epnstl bit is set, the usb function module sets the internal status bit and returns a stall handshake to the host (1-3 in figure 14.20). once an internal status bit is set, it remains set until cleared by a clear feature command from the host, without regarding to epnstl. even after a bit is cleared by the clear feature command (3-1 in figure 14.20), the usb function module continues to return a stall handshake while the epnstl bit is set, since the internal status bit is set each time a transaction is executed for the corresponding endpoint (1-2 in figure 14.20). to clear a stall, therefore, it is necessary for the corresponding epnstl bit to be cleared by the firmware, and also for the internal status bit to be cleared with a clear feature command (2-1 to 2-3 in figure 14.20).

section 14 universal serial bus (usb) rev.6.00 jun. 03, 2008 page 520 of 698 rej09b0074-0600 14.6 dma transfer specifications two methods of usb request and auto request are available for the dma transfer of usb data. 14.6.1 dmac transfer by usb request (1) overview only normal mode in full address mode (cycle steal mode) supports the transfer by a usb request of the on-chip dmac. endpoints that can be transferred by the on-chip dmac are ep1 and ep2 in bulk transfer (corresponding registers are uedr1 and uedr2). in dma transfer, the usb module must be accessed as an external device in area 6. the usb module cannot be accessed as a device with external ack (single-address transfer cannot be performed). 0-byte data transfer to ep2 is ignored even if the dma transfer is enabled by setting the ep2t1 bit in udmar to 1. (2) on-chip dmac settings the on-chip dmac must be specified as follows: a usb request ( dreq signal is used), activated by low-level input, byte size, full-address mode transfer, and the dta bit in dmabcr = 1. after completing the dma transfer of specified times, the dmac automatically stops. note, however, that the usb module keeps the dreq signal low while data to be transferred by the on-chip dmac remains regardless of the dmac status. (3) ep1 dma transfer the ep1t1 bit in udmar enables the dma transfer. the ep1t0 bit in udmar specifies the dreq signal to be used by the dma transfer. when 1 is written to the ep1t1 bit, the dreq signal is driven low if at least one of ep1 data fifos is empty; the dreq signal is driven high if both ep1 data fifos are full. (a) ep1pkte in utrg0 when dma transfer is performed on ep1 transmit data, the usb module automatically performs the same processing as writing 1 to ep1pkte if one data fifo (64 bytes) becomes full. accordingly, to transfer data of integral multiples of 64 bytes, the user needs not to write 1 to ep1pkte. to transfer data of less than 64 bytes, the user must write 1 to ep1pkte using the dma transfer end interrupt of the on-chip dmac. if the user writes 1 to ep1pkte in cases other than the case when data of less than 64 bytes is transferred, excess transfer occurs and correct operation cannot be guaranteed. figure 14.22 shows an example for transmitting 150 bytes of data from ep1 to the host. in this case, internal processing as the same as writing 1 to ep1pkte is automatically performed twice. this kind of internal processing is performed when the currently selected data fifo becomes full.
section 14 universal serial bus (usb) rev.6.00 jun. 03, 2008 page 521 of 698 rej09b0074-0600 accordingly, this processing is automatically performed only when 64-byte data is sent. this processing is not performed automatically when data less than 64 bytes is sent. (b) ep1 dma transfer procedure 1. set the bits ep1t1 and ep1t0 in udmar. 2. set dmac (specifies the number of transfers in dmac to transmit 150 bytes of data). 3. activate dmac. 4. perform dma transfer. 5. write 1 to the ep1pkte bit in utrg0 by a dma transfer end interrupt. 64 bytes 64 bytes 22 bytes ep1pkte (automatically performed) ep1pkte (automatically performed) ep1pkte is not performed executed by dma transfe r end interrupt (user) figure 14.22 ep1pkte operation in utrg0 (4) ep2 dma transfer the ep2t1 bit in udmar enables the dma transfer. the ep2t0 bit in the udmar specifies the dreq signal to be used by the dma transfer. when 1 is written to the ep2t1 bit, the dreq signal is driven low if at least one of ep2 data fifos is full (ready state); the dreq signal is driven high if both ep2 data fifos are empty when all receive data items are read. (a) ep2rdfn in utrg0 when dma transfer is performed on ep2 receive data, do not write 1 to ep2rdfn after one data fifo (64 bytes) has been read. in data transfer other than dma transfer, the next data cannot be read after one data fifo (64 bytes) has been read unless 1 is written to ep2rdfn. while in dma transfer, the usb module automatically performs the same processing as writing 1 to ep2rdfn if the currently selected data fifo becomes empty. accordingly, in dma tr ansfer, the user needs not to write 1 to ep2rdfn. if the user writes 1 to ep2rdfn in dma transfer, excess transfer occurs and correct operation cannot be guaranteed. figure 14.23 shows an example of ep2 receiving 150 bytes of data from the host. in this case, internal processing as the same as writing 1 to ep2rdfn is automatically performed three times. this kind of internal processing is performed when the currently selected data fifo becomes empty. accordingly, this processing is automatically performed both when 64-byte data is sent and when data less than 64 bytes is sent.

(2) on-chip dmac settings the on-chip dmac must be specified as follows: auto-request, byte size, full-address mode transfer, and number of transfers equal to or less than the maximum packet size of the data register. after completing the dmac transfers of specified time, the dmac automatically stops.

section 14 universal serial bus (usb) rev.6.00 jun. 03, 2008 page 528 of 698 rej09b0074-0600 14.8.4 setup data reception the following must be noted for the ep0s fifo used to receive 8-byte setup data. the usb is designed to always receive setup commands. acco rdingly, write from the udc has higher priority than read from the lsi. if the reception of the ne xt setup command starts while the lsi is reading data after completing reception, this data read from the lsi is forcibly cancelled and the next setup command write starts. after the next setup command write, data read from the lsi is thus undefined. read operation is forcib ly disabled because data cannot be guaranteed if dp-ram used as fifo accesses the same address for write and read. 14.8.5 fifo clear if the usb cable is disconnected during communication, old data may be contained in the fifo. accordingly, fifos must be cleared immediately after usb cable connection. in addition, after bus reset, all fifos must also be cleared. note, however, that fifos that are currently used for data transfer to or from the host must not be cleared. 14.8.6 irq6 interrupt a suspend/resume interrupt requested by irq6 must be specified as falling-edge sensitive. 14.8.7 data register overread or overwrite when the cpu reads or writes to data registers, the following must be noted: ? transmit data registers (uedr0i, uedr3, uedr1) data to be written to the transmit data registers must be within the maximum packet size. for the transmit data register of ep1 having a dual-fifo configuration, data to be written at any time must be within the maximum packet size. in this case, after a data write, the fifo is switched to the other fifo, enabling an further data write, when the pkte bit in utrg0 is set to 1. accordingly, data of size corresponding to two fifos must not be written to the transmit data registers at a time. ? receive data registers (uedr0o, uedr2) receive data registers must not read a data size that is greater than the effective size of the read data item. in other words, receive data registers must not read data with data size larger than that specified by the receive data size register. for the receive data register of ep2 having a dual-fifo configuration, data to be read at an y time must be within the maximum packet size. in this case, after reading the currently selected fifo, set the rdfn bit in utrg to 1. this switches the fifo to the other fifo and updates the receive data size, enabling the next data read. in addition, if there is no receive data in a fifo, data must not be read. otherwise, the
section 14 universal serial bus (usb) rev.6.00 jun. 03, 2008 page 529 of 698 rej09b0074-0600 pointer that controls the internal module fifo is updated and correct operation cannot be guaranteed. 14.8.8 reset ? the manual reset during usb communication operations must not be executed, since the lsi may stop with the state of usd+ and usd- pins maintained. this usb module uses synchronous reset for some registers. the reset state of these registers must be cancelled after the clock oscillation stabilization time has passed. at initialization, reset must be cancelled using the following procedure: 1. cancel the usb module stop 1: clear the usbstop1 bit in exmdlstp to 0. 2. select the usb operating clock: write 1 to the ucks3 to ucks0 bits in uctlr. 3. cancel the usb module stop 2: clear the mstpb0 bit in mstpcrb to 0. 4. wait for the usb operating clock stabilization: wait until the ck48ready bit in uifr3 is set to 1. 5. cancel the usb interface reset state: clear the uifrst bit in uctlr to 0. 6. cancel the udc core reset state: clear the udcrst bit in uctlr to 0. for details, see the flowcharts in section 14.5. 1, initialization and section 14.5.2, usb cable connection/disconnection. ? the usb registers are not initialized when the watchdog timer (wdt) triggers a power-on reset. therefore, the usb may not operate properly after a power-on reset is triggered by the wdt due to cpu runaway or a similar cause. (if a power-on reset is triggered by input of a power-on reset signal from the res pin, the usb registers are initialized and there is no problem.) consequently, an initialization routine should be used to write the initial values listed below to the following three registers, thereby ensuring that all the usb registers are properly initialized, immediately following a reset. uctlr = h'03, uier3 = h'80, uifr3 = h'00 14.8.9 ep0 interrupt sources assignment ep0 interrupt sources assigned to bits 3 to 0 in uifr0 must be assigned to the same interrupt signal ( exirqx ) by setting uisr0. there are no other restrictions on interrupt sources.
section 14 universal serial bus (usb) rev.6.00 jun. 03, 2008 page 530 of 698 rej09b0074-0600 14.8.10 level shifter for vbus and irqx pins the vbus and irqx pins of this usb module must be connected to the usb connector?s vbus pin via a level shifter. this is because the usb module has a circuit that operates by detecting usb cable connection or disconnection. even if the power of the device incorporating this usb module is turned off, 5-v power is applied to the usb connector?s vbus pin while the usb cab le is connected to the device set. to protect the lsi from destruction, use a level shifter such as the hd74lv-a series, which allows voltage application to the pin even when the power is off. 14.8.11 usb endpoint data read and write to write data to an usb endpoint data register (uedr0i, uedr1, or uedr3) on the transmit side using a cpu word or longword transfer instruction, the size of data to be written must be smaller than the size of data that is to be transmitted. for example, when 7-byte data is transferred to the host, 8-byte data is sent to the host if data is written twice by the longword transfer instructions or if data is written four times by the word transfer instructions. to write 7-byte data correctly, data must be written once by a longword transfer instruction, once by a word transfer instru ction, and once by a byte transfer instruction, or data must be written three times by a word transfer instruction and once by a byte transfer instruction. to read data from the usb endpoint data register (uedr0o or uedr2) on the receive side, the correct size of data must be read. in this case, the data size is specified by the usb endpoint receive size register (uesz0o or uesz2). to execute dma transfer on data in the usb endpoint data register using the on-chip dmac, byte transfer musts be used. in word transfer, odd-byte data cannot be transferred. word transfer is thus disabled. 14.8.12 restrictions on entering and canceling power-down mode before entering the power-down mode, set the usb module stop 2 state. the udc core must not be reset. to access the usb module after canceling power-down mode, cancel the usb module stop 2 state and wait for the usb operating clock (48 mhz) stabilization time.

section 17 flash memory (f-ztat version) rev.6.00 jun. 03, 2008 page 583 of 698 rej09b0074-0600 17.9 program/erase protection there are three kinds of flash memory program/erase protection: hardware protection, software protection, and error protection. 17.9.1 hardware protection hardware protection refers to a state in which programming/erasing of flash memory is forcibly disabled or aborted because of a transition to reset or standby mode. flash memory control register 1 (flmcr1), flash memory control regist er 2 (flmcr2), erase block register 1 (ebr1), and erase block register 2 (ebr2) are initialized. in a reset via the res pin, the reset state is not entered unless the res pin is held low until oscillation stabilizes after powering on. in the case of a reset during operation, hold the res pin low for the res pulse width specified in the ac characteristics section. 17.9.2 software protection software protection can be implemented against programming/erasing of all flash memory blocks by clearing the swe1 bit in flmcr1. when softwa re protection is in effect, setting the p1 or e1 bit in flmcr1 does not cause a transition to program mode or erase mode. by setting the erase block register 1 (ebr1), and erase block register 2 (ebr2), erase protection can be set for individual blocks. when ebr1 and ebr2 are set to h'00, erase protection is set for all blocks. 17.9.3 error protection in error protection, an error is detected when the cpu's runaway occurs during flash memory programming/erasing, or operation is not performed in accordance with the program/erase algorithm, and the program/erase operation is aborted. aborting the program/erase operation prevents damage to the flash memory due to overprogramming or overerasing. when the following errors are detected during programming/erasing of flash memory, the fler bit in flmcr2 is set to 1, and the error protection state is entered. setting conditions of fler bit (erase protection) ? when the flash memory of the relevant address area is read during programming/erasing (including vector read and instruction fetch) ? immediately after exception handling (excluding a reset) during programming/erasing ? when a sleep instruction is executed during programming/erasing ? when the cpu releases the bus mastership to the dmac during programming/erasing
section 17 flash memory (f-ztat version) rev.6.00 jun. 03, 2008 page 584 of 698 rej09b0074-0600 the flmcr1, flmcr2, ebr1 and ebr2 settings are retained, but program mode or erase mode is aborted at the point at which the error occurred. program mode or erase mode cannot be re- entered by re-setting the p1 or e1 bit. however, pv1 and ev1 bit setting is enabled, and a transition can be made to verify mode. 17.10 interrupt handling when programming/erasing flash memory all interrupts, including nmi interrupt is disabled when flash memory is being programmed or erased (when the p1 or e1 bit is set in flmcr1), and while the boot program is executing in boot mode* 1 , to give priority to the program or eras e operation. there are three reasons for this: 1. interrupt during programming or erasing might cause a violation of the programming or erasing algorithm, with the result that normal operation could not be assured. 2. in the interrupt exception handling sequence during programming or erasing, the vector would not be read correctly* 2 , possibly resulting in cpu runaway. 3. if interrupt occurred during boot program execution, it would not be possible to execute the normal boot mode sequence. notes: 1. interrupt requests must be disabled inside and outside the cpu until the programming control program has completed programming. 2. the vector may not be read correctly in this case for the following two reasons: ? if flash memory is read while being programmed or erased (while the p1 or e1 bit is set in flmcr1), correct read data will not be obtained (undetermined values will be returned). ? if the interrupt entry in the vector table has not been programmed yet, interrupt exception handling will not be executed correctly.

section 17 flash memory (f-ztat version) rev.6.00 jun. 03, 2008 page 588 of 698 rej09b0074-0600 ? use the recommended algorithm when programming and erasing flash memory. the recommended algorithm enables programmi ng and erasing to be carried out without subjecting the device to voltage stress or sacrificing program data reliability. when setting the p1 or e1 bit in flmcr1, the watchdog timer should be set beforehand as a precaution against program runaway, etc. ? do not set or clear the swe1 bit during execution of a program in flash memory. wait at least s* after clearing the swe1 bit before executing a program or reading data in flash memory. when the swe1 bit is set, data in flash memory can be rewritten, but access flash memory only for verify operations (verification during programming/erasing). also, do not clear the swe1 bit during programming, erasing, or verifying. similarly, when using emulation by ram with a high level applied to the fwe pin, the swe1 bit should be cleared before executing a program or reading data in flash memory. however, read/write accesses can be performed in the ram area overlapping the flash memory space regardless of whether the swe1 bit is set or cleared. note: * refer to section 22.7, flash memory characteristics. ? do not use interrupts while flash memory is being programmed or erased. all interrupt requests, including nmi, should be disabled during fwe application to give priority to program/erase operations. ? do not perform additional programming. erase the memory before reprogramming. in on-board programming, perform only one programming operation on a 128-byte programming unit block. in programmer mode, too, perform only one programming operation on a 128-byte programming unit block. programming should be carried out with the entire programming unit block erased. ? before programming, check that the chip is correctly mounted in the prom programmer. overcurrent damage to the device can result if the index marks on the prom programmer socket, socket adapter, and ch ip are not correctly aligned. ? do not touch the socket adapter or chip during programming. touching either of these can cause contact faults and write errors. ? the reset state must be entered after powering on apply the reset signal for at least 100 s during the oscillation setting period. ? when a reset is applied during operation, this should be done while the swe1 pin is low. wait at least s* after clearing the swe1 bit before applying the reset. note: * refer to section 22.7, flash memory characteristics.
