MACHINE INSTRUCTIONS (INDEX BY ALPHABET) (continued)
SNZT1 (Skip if Non Zero condition of Timer 1 interrupt request flag)
1010000000

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)

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)

Grouping:
Serial interface operation
Description: Clears (0) to SIOF flag and starts serial in-
terface.
Operation:
(SIOF) ← 0
Serial interface transmit/receive starting
