11.13.32 PIR9

Peripheral Interrupt Request Register 9
Note:
  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 will ensure the appropriate interrupt flag bits are clear prior to enabling an interrupt.
  2. U3IF is a read-only bit. To clear the interrupt condition, all bits in the U3UIR register must be cleared.
  3. U3EIF is a read-only bit. To clear the interrupt condition, all bits in the U3ERR register must be cleared.
  4. U3TXIF and U3RXIF are read-only bits and cannot be set/cleared by software.
