11.13.35 PIR12
Note:
- 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.
- U4IF is a read-only bit. To clear the interrupt condition, all bits in the U4UIR register must be cleared.
- U4EIF is a read-only bit. To clear the interrupt condition, all bits in the U4ERR register must be cleared.
- U4TXIF and U4RXIF are read-only bits and cannot be set/cleared by software.
