Detailed description

−−

Transfers the high-order 4 bits of prescaler to register B.

Transfers the low-order 4 bits of prescaler to register A.

−−

Transfers the contents of register B to the high-order 4 bits of prescaler and prescaler reload register RPS.

Transfers the contents of register A to the low-order 4 bits of prescaler and prescaler reload register RPS.

−−

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.

Transfers the low-order 4 bits (T23

−T20) of timer 2 to register A.

−−

Transfers the contents of register B to the high-order 4 bits (R2L7

−R2L4) of timer 2 and timer 2 reload register

R2L. Transfers the contents of register A to the low-order 4 bits (R2L3

−R2L0) of timer 2 and timer 2 reload

−−

Transfers the contents of register B to the high-order 4 bits (R2H7

−R2H4) of timer 2 and timer 2 reload

−R2H0) of timer 2 and timer 2

reload register R2H.

−−

Transfers the contents of timer 2 reload register R2L to timer 2.

−−

Transfers the contents of register A to timer LC and reload register RLC.

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)
