V12 = 1 : SNZT1 = NOP
(V12 = bit 2 of interrupt control register V1)
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 instruction.
When V12 = 1 : This instruction is equivalent to the NOP
instruction.

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 instruction.
When V13 = 1 : This instruction is equivalent to the NOP

next instruction when timer 3 interrupt request flag T3F is
“1”. When the T3F flag is “0”, executes the next instruction.
When V20 = 1 : This instruction is equivalent to the NOP
instruction.

Description: Skips the next instruction when voltage drop detection cir-
cuit flag VDF is “1”. Execute instruction when VDF is “0”.
After skipping, the contents of VDF remains unchanged.
