PIR9

Peripheral Interrupt Request Register 9
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.I3C2RIF is a read-only bit.
  3. 3.I3C2EIF is a read-only bit. To clear the interrupt condition, all bits in the I3C1ERRIRx registers must be cleared.
  4. 4.I3C2IF is a read-only bit. To clear the interrupt condition, all bits in the I3C1PIRx registers must be cleared.
  5. 5.I3C2TXIF is a read-only bit. The interrupt flag is cleared when I3CxTXB Transmit Buffer becomes full.
  6. 6. I3C2RXIF is a read-only bit. The interrupt flag is cleared when I3CxRXB Receive Buffer becomes empty.
