MACHINE INSTRUCTIONS (INDEX BY ALPHABET) (continued)

SNZT1 (Skip if Non Zero condition of Timer 1 interrupt request flag)

1010000000

280

–

V12 = 0: (T1F) = 1

Grouping:

Timer operation

Description: When V12 = 0 : Clears (0) to the T1F flag

and skips the next instruction when timer 1

interrupt request flag T1F is “1.” When the

T1F flag is “0,” executes the next instruc-

tion.

When V12 = 1 : This instruction is equiva-

lent to the NOP instruction.

Operation:

V12 = 0: (T1F) = 1 ?

(T1F)

← 0

V12 = 1: SNZT1 = NOP

(V12 = bit 2 of interrupt control register V1)

SNZT2 (Skip if Non Zero condition of Timer 2 interrupt request flag)

1010000001

281

–

V13 = 0: (T2F) = 1

Grouping:

Timer operation

Description: When V13 = 0 : Clears (0) to the T2F flag

and skips the next instruction when timer 2

interrupt request flag T2F is “1.” When the

T2F flag is “0,” executes the next instruc-

tion.

When V13 = 1 : This instruction is equiva-

lent to the NOP instruction.

Operation:

V13 = 0: (T2F) = 1 ?

(T2F)

← 0

V13 = 1: SNZT2 = NOP

(V13 = bit 3 of interrupt control register V1)

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 ?

SNZI0 (Skip if Non Zero condition of external 0 Interrupt input pin)

0000111010

03A

–

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)
