V12 = 0: (T1F) = 1
Grouping:
Timer operation
Description: When V12 = 0 : Skips the next instruction
when timer 1 interrupt request flag T1F is
“1.” After skipping, clears (0) to the T1F
flag. When the T1F flag is “0,” executes the
next instruction.
When V12 = 1 : This instruction is equiva-
lent to the NOP instruction.
Operation:
V12 = 0: (T1F) = 1 ?
After skipping, (T1F)
← 0
V12 = 1: SNZT1 = NOP
(V12 = bit 2 of interrupt control register V1)

V13 = 0: (T2F) = 1
Grouping:
Timer operation
Description: When V13 = 0 : Skips the next instruction
when timer 2 interrupt request flag T2F is
“1.” After skipping, clears (0) to the T2F
flag. When the T2F flag is “0,” executes the
next instruction.
When V13 = 1 : This instruction is equiva-
lent to the NOP instruction.
Operation:
V13 = 0: (T2F) = 1 ?
After skipping, (T2F)
← 0
V13 = 1: SNZT2 = NOP
(V13 = bit 3 of interrupt control register V1)

V20 = 0: (T3F) = 1
Grouping:
Timer operation
Description: When V20 = 0 : Skips the next instruction
when timer 3 interrupt request flag T3F is
“1.” After skipping, clears (0) to the T3F
flag. When the T3F flag is “0,” executes the
next instruction.
When V20 = 1 : This instruction is equiva-
lent to the NOP instruction.
Operation:
V20 = 0: (T3F) = 1 ?
After skipping, (T3F)
← 0
V20 = 1: SNZT3 = NOP
(V20 = bit 0 of interrupt control register V2)

V23 = 0: (SIOF) = 1
Grouping:
Serial I/O operation
Description: When V23 = 0 : Skips the next instruction
when serial I/O interrupt request flag SIOF
is “1.” After skipping, clears (0) to the SIOF
flag. When the SIOF flag is “0,” executes
the next instruction.
When V23 = 1 : This instruction is equiva-
lent to the NOP instruction.
Operation:
V23 = 0: (SIOF) = 1 ?
After skipping, (SIOF)
← 0
V23 = 1: SNZSI = NOP
(V23 = bit 3 of interrupt control register V2)
