Skip condition

Detailed description

−−

Clears (0) to interrupt enable flag INTE, and disables the interrupt.

−−

Sets (1) to interrupt enable flag INTE, and enables the interrupt.

V10 = 0 : (EXF0) = 1

−

When V10 = 0 : Clears (0) to the EXF0 flag and skips the next instruction when external 0 interrupt request

flag EXF0 is “1”. When the EXF0 flag is “0”, executes the next instruction.

When V10 = 1 : This instruction is equivalent to the NOP instruction. (V10: bit 0 of interrupt control register

V1)

(INT0) =

“L”

However, I12 = 0

−

When I12 = 0 : Skips the next instruction when the level of INT0 pin is “L”. Executes the next instruction when

the level of INT0 pin is “H”.

(INT0) =

“H”

However, I12 = 1

When I12 = 1 : Skips the next instruction when the level of INT0 pin is “H”. Executes the next instruction when

the level of INT0 pin is “L”. (I12: bit 2 of interrupt control register I1)

V11 = 0 : (EXF1) = 1

−

When V11 = 0 : Clears (0) to the EXF1 flag and skips the next instruction when external 1 interrupt request

flag EXF1 is “1”. When the EXF1 flag is “0”, executes the next instruction.

When V11 = 1 : This instruction is equivalent to the NOP instruction. (V11: bit 1 of interrupt control register

V1)

I22 = 0 :

(INT1) =

“L”

−

When I22 = 0 : Skips the next instruction when the level of INT1 pin is “L”. Executes the next instruction when

the level of INT1 pin is “H”.

I22 = 1 :

(INT1) =

“H”

When I22 = 1 : Skips the next instruction when the level of INT1 pin is “H”. Executes the next instruction when

the level of INT1 pin is “L”. (I22: bit 2 of interrupt control register I2)

−−

Transfers the contents of interrupt control register V1 to register A.

−−

Transfers the contents of register A to interrupt control register V1.

−−

Transfers the contents of interrupt control register V2 to register A.

−−

Transfers the contents of register A to interrupt control register V2.

−−

Transfers the contents of interrupt control register I1 to register A.

−−

Transfers the contents of register A to interrupt control register I1.

−−

Transfers the contents of interrupt control register I2 to register A.

−−

Transfers the contents of register A to interrupt control register I2.

−−

Transfers the contents of register A (A1, A0) to timer control register PA.

−−

Transfers the contents of timer control register W1 to register A.

−−

Transfers the contents of register A to timer control register W1.

−−

Transfers the contents of timer control register W2 to register A.

−−

Transfers the contents of register A to timer control register W2.

−−

Transfers the contents of timer control register W3 to register A.

−−

Transfers the contents of register A to timer control register W3.

−−

Transfers the contents of timer control register W5 to register A.

−−

Transfers the contents of register A to timer control register W5.
