Contents
Register A (4 bits)
Register B (4 bits)
Carrier wave select register C (3 bits)
Register D (3 bits)
Register E (8 bits)
Machine cycle count value select register MC
(1 bit)
Logic operation select register (2 bits)
Register X (2 bits)
Register Y (4 bits)
Data pointer (6 bits)
(consisting of the registers X and Y)
Program counter (10 bits)
The upper 3 bits of the program counter
The lower 7 bits of the program counter
Stack registers (10 bits
× 4)
Stack pointer (2 bits)
Carry flag (1 bit)
Machine cycle counter overflow flag
Powerdown flag
Port D(8 bits)
Port E(1 bit)
Port G(4 bits)
Port CARR (1 bit)
Note: M34238MK-XXXGP just invalidates the next instruction when a skip is performed. The contents of program counter is not increased.
Therefore, the cycle number does not change, regardless of whether a skip is generated or not.
However, if TABP p, RT, or RTS instruction is skipped, the cycle number becomes “1”.
