V12 = 0 : (T1F) = 1
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.
(V12: bit 2 of interrupt control register V1)
V13 = 0 : (T2F) = 1
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 instruction.
(V13: bit 3 of interrupt control register V1)
V20 = 0 : (T3F) = 1
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 instruction.
When V20 = 1 : This instruction is equivalent to the NOP instruction.
(V20: bit 0 of interrupt control register V2)
