V21 = 0: (T4F) = 1
Grouping:
Timer operation
Description: When V21 = 0 : Skips the next instruction
when timer 4 interrupt request flag T4F is
“1.” After skipping, clears (0) to the T4F
flag. When the T4F flag is “0,” executes the
next instruction.
When V21 = 1 : This instruction is equiva-
lent to the NOP instruction.
Operation:
V21 = 0: (T4F) = 1 ?
After skipping, (T4F)
← 0
V21 = 1: SNZT4 = NOP
(V21 = bit 1 of interrupt control register V2)

Grouping:
Bit operation
Description: Skips the next instruction when the con-
tents of bit j (bit specified by the value j in
the immediate field) of M(DP) is “0.”
Executes the next instruction when the con-
tents of bit j of M(DP) is “1.”
Operation:
(Mj(DP)) = 0 ?
