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
(INT0) = “L”
However, I12 = 0
(INT0) = “H”
However, I12 = 1
V11 = 0 : (EXF1) = 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)
− 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”.
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)
− 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”
I22 = 1 :
(INT1) = “H”
−
− 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”.
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.
