When the accumulator overflows, the NCO Interrupt Flag bit, NCOxIF, in the associated
PIR register is set. To enable interrupt service on this event, the following bits must
be set:
- EN bit
- NCOxIE bit in the associated PIE
register
- Peripheral and Global Interrupt
Enable bits
The interrupt must be cleared by software by clearing the NCOxIF bit in the
Interrupt Service Routine.
