PIR1 REGISTER

This register contains the individual flag bits for the

Peripheral interrupts.

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, GIE (INTCON<7>). User soft-

ware should ensure the appropriate inter-

rupt flag bits are clear prior to enabling an

interrupt.
