7.2 Operation Registers Description
7.2.1 R0 (Indirect Address Register)
R0 is not a physically implemented register. It is used as indirect address pointer. Any instruction using R0 as register actually accesses data pointed by the RAM Select Register (R4). Example: Mov A, @0x20 Mov 0x04, A Mov A, @0xAA Mov 0x00, A ;store an address at R4 for indirect address ;write data 0xAA to R20 at Bank0 through R0
7.2.2 R1 (TCC)
TCC data buffer. Increased by 16.384KHz or by the instruction cycle clock (controlled by CONT register). Written and read by the program as any other register.
7.2.3 R2 (Program Counter)
The structure is depicted in Fig.3 below. Generates 8k x 13 external ROM addresses to the relative programming instruction codes. "JMP" instruction allows the direct loading of the low 10 program counter bits. "CALL" instruction loads the low 10 bits of the PC, PC+1, and then push into the stack. "RET'' ("RETL k," "RETI") instruction loads the program counter with the contents at the top of stack. "MOV R2, A" allows the loading of an address from the A register to the PC, and the ninth and tenth bits are cleared to "0''. "ADD R2, A" allows a relative address to be added to the current PC, and contents of the ninth and tenth bits are cleared to "0''.

"TBL" allows a relative address to be added to the current PC, and the contents of the ninth and tenth bits do not change. The most significant bit (A10~A13) will be loaded with the contents of bit PS0~PS3 in the status register (R5 PAGE 1) upon execution of a "JMP," "CALL," "ADD R2, A." or "MOV R2, A'' instruction. If an interrupt is triggered, PROGRAM ROM will jump to address 0x08 at Page0. The CPU will automatically store ACC, R3 status, and R5 PAGE 1, and they will be restored after execution of instruction RETI.

Bit 0 (C) : Carry flag
The carry flag is affected by following operation : a. Addition : CF as a carry out indicator, when the addition operation has a carry-out, CF will be "1", in another word, if the operation has no carry-out, CF will be "0". b. Subtraction : CF as a borrow-in indicator, when the subtraction operation must has a borrow-in, the CF will be "0", in another word, if no borrow-in, CF will be "1". c. Comparision : CF is as a borrow-in indicator for Comparision operation as the same as subtraction operation. d. Rotation : CF shifts into the empty bit of accumulator for the rotation and holds the shift out data after rotation.
Bit 1 (DC) : Auxiliary carry flag Bit 2 (Z) : Zero flag
ZF is affected by the result of ALU, if the ALU operation generate a "0" result, the ZF will be "1", otherwise, the ZF will be "0".
Bit 3 (P) : Power down bit Set to 1 during power on or by a "WDTC" command and reset to 0 by a "SLEP" command.

7.4 Application notes
1B Call-table instruction:G
Because the call-table instruction can only change the Program Counter's bit7 ~ bit0 at each time, only 256 addresses can be searched once. But each program page contains 1024 addresses, if call each 256 addresses as a zone, Then each page constitutes by four zones. When a table overlaps two zones, a bug would occur during address searching. So the member of program must examine the .LST file at any time, the .LST file will jot down the information that Assembler generated, for example source code, the coding of instruction , instruction address, error message etc.
2B Operation requirement for the CPUG
The system frequency must adds a latency time ( 14.33 MHz about 250 ms F 17.91 MHz about 450 ms.). After RA register was setting, it will offer the stable system frequency for the operation.
3B The register initial sets to suggest
The register 0X0B of IOC page 0 & page 1 initial sets suggestion as follows 0x0B register value = 0x00 The register 0X0B of R page 0 initial sets suggestion as follows 0x0B register value = 0x00

7.5I/O Port
The I/O registers are bi-directional tri-state I/O ports. The I/O ports can be defined as "input" or "output" pins by the I/O control registers under program control. The I/O data registers and I/O control registers are both readable and writable. The I/O interface circuit is shown in Fig.22.

7.6 RESET
A RESET can be caused by any of the following: 1. Power on reset 2. WDT timeout (if enabled and in GREEN or NORMAL mode) 3. /RESET pin pull low Once a RESET occurs, the following functions are performed. The oscillator is running, or will be started. The Program Counter (R2) is set to all "0". When power on, the upper 3 bits of R3 and the upper 2 bits of R4 are cleared. The Watchdog timer and prescaler counter are cleared. The Watchdog timer is disabled. The CONT register is set to all "1"

7.7 Wake Up
The controller features two types of sleep mode for power saving:
7.7.1 SLEEP Mode, RA(6 ;7) = 0 + "SLEP" Instruction
Under this mode, the controller turns off all the CPU and crystal. However, other circuits with power control like key tone control or PLL control (with register enabled), has to be turned off through software.
7.7.2 IDLE mode, RA(6 ;7) = 1 + "SLEP" Instruction.
With this mode, the controller only turns the CPU off. The crystal remains running.
7.7.3 Wake-up from SLEEP Mode
1. WDT time out 2. External interrupt 3. /RESET pull low Any of these cases will reset the controller and run the program from address zero. The status is just like the power-on-reset condition. Be sure to enable circuit after cases 1 or 2 occurs.

7.7.4 Wake-up from IDLE Mode
1. WDT time out 2. External interrupt 3. Internal interrupt like counters All these cases requires you to enable the circuit before entering IDLE mode. All the registers values are preserved when "SLEP" instruction is executed and restored after wake-up. During execution of case 2 or 3, controller will wake up and jump to address 0x08 for interruption sub-routine. After performing the sub-routine ("RETI" instruction), the program will jump to the next instruction following the "SLEP" instruction.
7.8 Interrupts
RD, RE, and RF are the interrupt status registers which record the interrupt request in flag bit. IOCD, IOCE, & IOCF are their interrupt mask registers respectively. Global interrupt is enabled by ENI instruction and is disabled by DISI instruction. When one of the interrupts (when enabled) is generated, it will cause the next instruction to be fetched from address 008H. Once in the interrupt service routine, the source of the interrupt can be determined by polling the flag bits in their respective (RD, RE, and RF) registers. The interrupt flag bit must be cleared in the software before leaving the interrupt service routine and enabling interrupts to avoid recursive interrupts.
7.9 Instruction Set
The Instruction set has the following features: 1. Every bit of any register can be set, cleared, or tested directly. 2. The I/O register can be treated as a general register. That is, the same instruction can operates on I/O register. The symbol "R" represents a register designator which specifies which one of the 64 registers (including operational registers and general purpose registers) is to be utilized by the instruction. Bits 6 and 7 in R4 determine the selected register bank. "b'' represents a bit field designator which selects the number of the bit located in the Register "R," and affected by the operation. "k'' represents an 8 or 10-bit constant or literal value.

The first 1 byte (b0 to b7) inputted to the EPVP6200 through the DIN pin after the STB pin has fallen, is regarded as a command. Interrupt event will occur when STB pin is falling. If STB mode is high while a command/data are being transmitted, serial communication is initialized, and the command/data being transmitted is invalidated (however, the command/data already transmitted remain valid).
