4518 Group

SNZP (Skip if Non Zero condition of Power down flag)

0000000011

003

–

(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 ?

SNZAD (Skip if Non Zero condition of A/D conversion completion flag)

1010000111

287

–

V22 = 0: (ADF) = 1

Grouping:

A/D conversion operation

Description: When V22 = 0 : Skips the next instruction

when A/D conversion completion flag ADF

is “1.” After skipping, clears (0) to the ADF

flag. 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 ?

After skipping, (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

–

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)

SNZI1 (Skip if Non Zero condition of external 1 Interrupt input pin)

0000111011

03B

–

I22 = 0 : (INT1) = “L”

I22 = 1 : (INT1) = “H”

Grouping:

Interrupt operation

Description: When I22 = 0 : Skips the next instruction

when the level of INT1 pin is “L.” Executes

the next instruction when the level of INT1

pin is “H.”

When I22 = 1 : Skips the next instruction

when the level of INT1 pin is “H.” Executes

the next instruction when the level of INT1

pin is “L.”

Operation:

I22 = 0 : (INT1) = “L” ?

I22 = 1 : (INT1) = “H” ?

(I22 : bit 2 of the interrupt control register I2)
