PIR1 Register
The PIR1 register contains the Peripheral Interrupt
Flag bits, as shown in Register 13-4.
Note 1: 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) in the
INTCON register. The user’s software
should ensure the appropriate interrupt
flag bits are clear prior to enabling an
interrupt.
