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 × 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

"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 3 (PAB)
: Prescaler assignment bit
0/1
TCC/WDT
When in WDT mode (Bit 3 = 1), the prescaler is cleared by the WDTC and
SLEP instructions. Likewise, when in TCC mode (Bit 3 = 0), the prescaler
will can NOT be cleared by SLEP instructions.
An 8-bit counter is provided as prescaler for the TCC or WDT. The
prescaler is available for the TCC only or for the WDT only at a given time.
An 8 bit counter is made available for TCC or WDT as determined by the
status of Bit 3 (PAB) of the CONT register.
Both TCC and prescaler are cleared each time a write to TCC instruction is
executed. (See the table above for the prescaler ratio under CONT register
and Fig.7 below for the TCC/WDT block diagram.)
Bit 4 (RETBK)
: Return value backup control for interrupt routine
0/1
disable/enable
When this bit is set to 1, the CPU will store ACC, R3 status, and R5 PAGE 1
automatically after an interrupt is triggered. It will be restored after
instruction RETI. When this bit is set to 0, you need to store ACC, R3, and
R5 PAGE 1 in you program.

NOTES: 1. PORT90 interrupt function is controlled by IOCF Bit 3. It is a falling edge or rising edge
trigger (controlled by CONT register Bit7).
2. PORT9 (1~4) interrupt functions are controlled by IOCF Bits 4, 5, 6, & 7). They are falling
edge triggers.
3. STB interrupt source function is controlled by IOCE PAGE0 Bit 4. It is falling edge trigger
after the STB goes low.
7.4 Application notes
1、Call-table instruction:：
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.
2、Operation requirement for the CPU：
The system frequency must adds a latency time ( 14.33 MHz about 250 ms ；
17.91 MHz about 450 ms.). After RA register was setting, it will offer the stable
system frequency for the operation.
3、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

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

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.

VFD Controller
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).

This command initializes the ePVP6200 and selects Display mode number of segments and
grids (1/8 to 1/19-duty, 9 segments to 20 segments) as illustrated below.
When Display Mode command is executed, display is forcibly turned off, and key scanning is
also stopped. To resume display, a display ON command must be executed. If the same
Display mode is selected, nothing is performed.
When power is turned “ON,” default Display mode is “19-digit, 9-segment.”
