MACHINE INSTRUCTIONS (INDEX BY ALPHABET) (continued)
SNZ0 (Skip if Non Zero condition of external 0 interrupt request flag)
0000111000
038
11
–
V10 = 0: (EXF0) = 1
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 in-
struction.
When V10 = 1 : This instruction is equiva-
lent to the NOP instruction.
Operation:
V10 = 0: (EXF0) = 1 ?
(EXF0) ← 0
V10 = 1: SNZ0 = NOP
(V10 : bit 0 of the interrupt control register V1)
SEAM (Skip Equal, Accumulator with Memory)
0000100110
026
11
–
(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)) ?
SNZAD (Skip if Non Zero condition of A/D conversion completion flag)
1010000111
287
11
–
V22 = 0: (ADF) = 1
Grouping:
A/D conversion operation
Description: When V22 = 0 : Clears (0) to the ADF flag
and skips the next instruction when A/D
conversion completion flag ADF is “1.”
When the ADF flag is “0,” executes the next
instruction.
When V22 = 1 : This instruction is equiva-
lent to the NOP instruction.
Operation:
V22 = 0: (ADF) = 1 ?
(ADF) ← 0
V22 = 1: SNZAD = NOP
(V22 : bit 2 of the interrupt control register V2)
SNZI0 (Skip if Non Zero condition of external 0 Interrupt input pin)
0000111010
03A
11
–
I12 = 0 : (INT) = “L”
I12 = 1 : (INT) = “H”
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.”
Operation:
I12 = 0 : (INT) = “L” ?
I12 = 1 : (INT) = “H” ?
(I12 : bit 2 of the interrupt control register I1)
