11.13.20 PIR1
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 must ensure the appropriate interrupt flag bits are clear prior to enabling an interrupt.
- The external interrupt GPIO pin is selected by the INTxPPS register.
- I2C2EIF is a read-only bit. To clear the interrupt condition, all bits in the I2C2ERR register must be cleared.
- I2C2IF is a read-only bit. To clear the interrupt condition, all bits in the I2C2PIR register must be cleared.
- I2C2TXIF and I2C2RXIF are read-only bits. To clear the interrupt condition, the CLRBF bit in I2C2STAT1 must be set.
