Skip condition
V22 = 0: (ADF) = 1
Operation:
V22 = 0: (ADF) = 1 ?
After skipping, (ADF) â 0
V22 = 1: SNZAD = NOP
(V22 : bit 2 of the interrupt control register V2)
Grouping: A/D conversion operation
Description: When V22 = 0 : Skips the next instruction
when A/D conversion completion flag ADF
is â1.â After skipping, clears (0) to the ADF
flag. When the ADF flag is â0,â executes the
next instruction.
When V22 = 1 : This instruction is equiva-
lent to the NOP instruction.

â I12 = 0 : (INT0) = âLâ
I12 = 1 : (INT0) = âHâ
Operation:
I12 = 0 : (INT0) = âLâ ?
I12 = 1 : (INT0) = âHâ ?
(I12 : bit 2 of the interrupt control register I1)
Grouping: Interrupt operation
Description: When I12 = 0 : Skips the next instruction
when the level of INT0 pin is âL.â Executes
the next instruction when the level of INT0
pin is âH.â
When I12 = 1 : Skips the next instruction
when the level of INT0 pin is âH.â Executes
the next instruction when the level of INT0
pin is âL.â

I22 = 1 : (INT1) = âHâ ?
(I22 : bit 2 of the interrupt control register I2)
Grouping: Interrupt operation
Description: When I22 = 0 : Skips the next instruction
when the level of INT1 pin is âL.â Executes
the next instruction when the level of INT1
pin is âH.â
When I22 = 1 : Skips the next instruction
when the level of INT1 pin is âH.â Executes
the next instruction when the level of INT1
SNZP (Skip if Non Zero condition of Power down flag)
pin is âL.â

Skip condition
(P) = 1
Operation: (P) = 1 ?
Grouping: Other operation
Description: Skips the next instruction when the P flag is
â1â.
After skipping, the P flag remains un-
changed.
Executes the next instruction when the P
flag is â0.â
