Grouping:
Comparison operation
Description: Skips the next instruction when the contents of register A is
equal to the contents of M(DP).
Executes the next instruction when the contents of register
A is not equal to the contents of M(DP).

V10 = 1 : SNZ0 = NOP
(V10 : bit 0 of the interrupt control register V1)
Grouping:
Interrupt operation
Description: When V10 = 0 : Clears (0) to the EXF0 flag and skips the
next instruction when external 0 interrupt request flag
EXF0 is “1”. When the EXF0 flag is “0”, executes the next
instruction.
When V10 = 1 : This instruction is equivalent to the NOP
instruction.

(I12 : bit 2 of the interrupt control register I1)
Grouping:
Interrupt operation
Description: When I12 = 0 : Skips the next instruction when the level of
INT pin is “L”. Executes the next instruction when the level
of INT pin is “H”.
When I12 = 1 : Skips the next instruction when the level of
INT pin is “H.” Executes the next instruction when the level
of INT pin is “L”.

Grouping:
Other operation
Description: Skips the next instruction when the P flag is “1”.
After skipping, the P flag remains unchanged.
Executes the next instruction when the P flag is “0”.
