4.2.2.5 PIR1 REGISTER

Applicable Devices 710 71 711 715

This register contains the individual flag bits for the

Peripheral interrupts.

bit 7: Unimplemented: Read as '0'

bit 6:

ADIF: A/D Converter Interrupt Flag bit

1 = An A/D conversion completed

0 = The A/D conversion is not complete

bit 5-0: Unimplemented: Read as '0'

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.
