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 : Skips the next instruction when external 0 interrupt request flag EXF0 is “1.” After skipping,
clears (0) to the EXF0 flag. 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 V11 = 0 : Skips the next instruction when external 1 interrupt request flag EXF1 is “1.” After skipping,
clears (0) to the EXF1 flag. 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)
When I12 = 1 : Skips the next instruction when the level of INT0 pin is “H.” (I12: bit 2 of interrupt control reg-
ister I1)
When I12 = 0 : Skips the next instruction when the level of INT0 pin is “L.”
When I22 = 1 : Skips the next instruction when the level of INT1 pin is “H.” (I22: bit 2 of interrupt control reg-
ister I2)
When I22 = 0 : Skips the next instruction when the level of INT1 pin is “L.”
