1 Port 70 interrupt function is controlled by IOCF Bit 3. It is a falling edge or rising edge trigger (controlled by
CONT register Bit 7).
2 Port 71 interrupt function is controlled by IOCF Bit 4. It is a falling edge trigger.
3 Port 73 interrupt function is controlled by IOCF Bit 7. It is a falling edge trigger.
4 ADI interrupt source function is controlled by RE Page 0 Bit 5. It is a rising edge trigger after an ADC sampling
is completed.
