8.5.7 PIR3 REGISTER

The PIR3 register contains the interrupt flag bits, as

shown in Register 8-7.

Note 1: Interrupt flag bits are set when an inter-

rupt condition occurs, regardless of the

state of its corresponding enable bit or

the Global Interrupt Enable bit, GIE, of

the INTCON register. User software

should ensure the appropriate interrupt

flag bits are clear prior to enabling an

interrupt.
