MACHINE INSTRUCTIONS (INDEX BY ALPHABET) (continued)

SNZT3 (Skip if Non Zero condition of Timer 3 interrupt request flag)

1010000010

282

–

V20 = 0: (T3F) = 1

Grouping:

Timer operation

Description: When V20 = 0 : Clears (0) to the T3F flag

and skips the next instruction when timer 3

interrupt request flag T3F is “1.” When the

T3F flag is “0,” executes the next instruc-

tion.

When V20 = 1 : This instruction is equiva-

lent to the NOP instruction.

Operation:

V20 = 0: (T3F) = 1 ?

(T3F)

← 0

V20 = 1: SNZT3 = NOP

(V20 = bit 0 of interrupt control register V2)
