7.6.6 PIR2 REGISTER
The PIR2 register contains the interrupt flag bits, as
shown in Register 7-6.
Note:
Interrupt flag bits are set when an interrupt
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.
