–
V10 = 0: (EXF0) = 1
Grouping:
Interrupt operation
Description: When V10 = 0 : Skips the next instruction
when external 0 interrupt request flag EXF0
is “1.” After skipping, clears (0) to the EXF0
flag. When the EXF0 flag is “0,” executes
the next instruction.
When V10 = 1 : This instruction is equiva-
lent to the NOP instruction.
Operation:
V10 = 0: (EXF0) = 1 ?
After skipping, (EXF0)
← 0
V10 = 1: SNZ0 = NOP
(V10 : bit 0 of the interrupt control register V1)

Grouping:
Comparison operation
Description: Skips the next instruction when the con-
tents of register A is equal to the value n in
the immediate field.
Executes the next instruction when the con-
tents of register A is not equal to the value n
in the immediate field.
Operation:

Executes the next instruction when the con-
tents of register A is not equal to the
contents of M(DP).
