PORT70 's interrupt function is controlled by IOCF bit 3. It's falling edge or rising edge trigger (controlled
by CONT register bit7).
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.
ADI interrupt source function is controlled by RE PAGE0 bit 5. It is rising edge trigger after ADC
sample complete.
