11.13.26 PIR8

Peripheral Interrupt Request Register 8
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 must ensure the appropriate interrupt flag bits are clear prior to enabling an interrupt.
  2. U2IF is a read-only bit. To clear the interrupt condition, all bits in the U2UIR register must be cleared.
  3. U2EIF is a read-only bit. To clear the interrupt condition, all bits in the U2ERR register must be cleared.
  4. U2TXIF and U2RXIF are read-only bits and cannot be set/cleared by software.
