Bit 0 ~ 3 ; Bit 7 : interrupt enable bit
0 Î disable interrupt
1 Î enable interrupt
Bit 4~Bit6 : (remain these values to “0”othwise it will generate unpredicted interrupts)
The status after interrupt and the interrupt sources list as the table below.

<Note> PORT70 's interrupt function is controlled by IOCF bit 3. It's falling edge or rising edge trigger
(controlled by CONT register bit7).
PORT73 's interrupt function is controlled by IOCF bit 7. They are falling edge trigger.
ADI interrupt source function is controlled by RE PAGE0 bit 5. It is rising edge trigger after ADC
sample complete.
<ps> It only happens when master and 16.386kHz mode is selected.
