Note:
PIC16F785/HV785
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).
User software should ensure the appropri-
ate interrupt flag bits are clear prior to
enabling an interrupt.
