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.” After
skipping, . When the ADF flag is “0,” ex-
ecutes 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)
SNZP (Skip if Non Zero condition of Power down flag)
0000000011
003
11
–
(P) = 1
Grouping:
Other operation
Description: Skips the next instruction when the P flag is
“1”.
After skipping, the P flag remains un-
changed.
Executes the next instruction when the P
flag is “0.”
Operation:
(P) = 1 ?

SNZSI (Skip if Non Zero condition of Serial Interface interrupt request flag)
1010001000

–
V23 = 0: (SIOF) =1
Grouping:
Serial interface operation
Description: Clears (0) to SIOF flag and skips the next
instruction when the contents of bit 3 (V23)
of interrupt control register V2 is “0” and
contents of SIOF flag is “1.”
When V23 = 1: This instruction is equivalent
to the NOP instruction.
Operation:
V23=0: (SIOF)=1?
(SIOF) ← 0
V23 = 1: SNZSI = NOP
