PIR3

PIR3

Peripheral Interrupt Request Register 3
Notes:
  1. 1. Interrupt flag bits get set when an interrupt condition occurs, regardless of the state of its corresponding enable bit, or the global enable bit. User software must ensure the appropriate interrupt flag bits are clear prior to enabling an interrupt.
  2. 2.IOCIF is a read-only bit. To clear the interrupt condition, all bits in the IOCxF registers must be cleared.
  3. 3.The CSWIF interrupt will not wake the system from Sleep. The system will Sleep until another interrupt causes the wake-up.
