–
I12 = 0 : (INT0) = “L”
I12 = 1 : (INT0) = “H”
Grouping:
Interrupt operation
Description: When I12 = 0 : Skips the next instruction
when the level of INT0 pin is “L.” Executes
the next instruction when the level of INT0
pin is “H.”
When I12 = 1 : Skips the next instruction
when the level of INT0 pin is “H.” Executes
the next instruction when the level of INT0
pin is “L.”
Operation:
I12 = 0 : (INT0) = “L” ?
I12 = 1 : (INT0) = “H” ?
(I12 : bit 2 of the interrupt control register I1)
SNZ0 (Skip if Non Zero condition of external 0 interrupt request flag)

–
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)

–
(A) = (M(DP))
Grouping:
Comparison operation
Description: Skips the next instruction when the con-
tents of register A is equal to the contents of
M(DP).
Executes the next instruction when the con-
tents of register A is not equal to the
contents of M(DP).
Operation:
(A) = (M(DP)) ?

V11 = 0: (EXF1) = 1
Grouping:
Interrupt operation
Description: When V11 = 0 : Skips the next instruction
when external 1 interrupt request flag EXF1
is “1.” After skipping, clears (0) to the EXF1
flag. When the EXF1 flag is “0,” executes
the next instruction.
When V11 = 1 : This instruction is equiva-
lent to the NOP instruction.
Operation:
V11 = 0: (EXF1) = 1 ?
After skipping, (EXF1)
← 0
V11 = 1: SNZ1 = NOP
(V11 : bit 1 of the interrupt control register V1)
