PIR1 REGISTER

This register contains the individual 铿俛g bit for the

comparator interrupt.

Note:

Interrupt 铿俛g 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

software should ensure the appropriate

interrupt 铿俛g bits are clear prior to enabling

an interrupt.
