11.13.19 PIR1

Peripheral Interrupt Request Register 1

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.
