V10 = 0: (EXF0) = 1

(INT) = “H”

However, I12 = 1

(INT) = “L”

However, I12 = 0

–

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

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

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)

When I12 = 1 : Skips the next instruction when the level of INT pin is “H.” (I12: bit 2 of interrupt control reg-

ister I1)

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

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.
