PIR3 REGISTER(1)

The PIR3 register contains the interrupt flag bits, as

shown in Register 8-8.

Note 1: The PIR3 register is available only on the

PIC16F/LF1827 device.

2: Interrupt flag bits are set when an inter-

rupt condition occurs, regardless of the

state of its corresponding enable bit or the

Global Enable bit, GIE, of the INTCON

register. User software should ensure the

appropriate interrupt flag bits are clear

prior to enabling an interrupt.
