Transfers the high-order 4 bits (T17
T14) of timer 1 to register B.
Transfers the low-order 4 bits (T13
T10) of timer 1 to register A.
Transfers the contents of register B to the high-order 4 bits of timer 1 and timer 1 reload register R1L.
Transfers the contents of register A to the low-order 4 bits of timer 1 and timer 1 reload register R1L.
Transfers the contents of register B to the high-order 4 bits (R17
R14) of reload register R1, and the contents
of register A to the low-order 4 bits (R13
R10) of reload register R1.
Transfers the high-order 4 bits (T27
T24) of timer 2 to register B.

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)
