Bit7
Bit 0~1; 3~4 ; Bit 7 : interrupt enable bit
Bit 2, 5~6 : (remain these values to “0”othwise it will generate unpredicted interrupts)
0 Î disable interrupt
1 Î enable interrupt
The status after interrupt and the interrupt sources list as the table below.
PORT70 's interrupt function is controlled by IOCF bit 3. It's falling edge or rising edge trigger (controlled
PORT71 's interrupt function is controlled by IOCF bit 4. It’s falling edge trigger.
PORT73 's interrupt function is controlled by IOCF bit 7. They are falling edge trigger.
by CONT register bit7).
ADI interrupt source function is controlled by RE PAGE0 bit 5. It is rising edge trigger after ADC
sample complete.
