PIR4 REGISTER
The PIR4 register contains the interrupt flag bits, as
shown in Register 7-9.
Note:
Interrupt flag bits are set when an interrupt
condition occurs, regardless of the state of
its corresponding enable bit or the Global
Enable bit, GIE, of the INTCON register.
User
software
should
ensure
the
appropriate interrupt flag bits are clear prior
to enabling an interrupt.
