PIR1 Register
PIR1 — PERIPHERAL INTERRUPT REGISTER 1 (ADDRESS: 0Ch)
bit 7
EEIF: EEPROM Write Operation Interrupt Flag bit
1 = The write operation completed (must be cleared in software)
0 = The write operation has not completed or has not been started
ADIF: A/D Converter Interrupt Flag bit (PIC16F676 only)
1 = The A/D conversion is complete (must be cleared in software)
0 = The A/D conversion is not complete
Unimplemented: Read as ‘0’
CMIF: Comparator Interrupt Flag bit
1 = Comparator input has changed (must be cleared in software)
0 = Comparator input has not changed
Unimplemented: Read as ‘0’
TMR1IF: TMR1 Overflow Interrupt Flag bit
1 = TMR1 register overflowed (must be cleared in software)
0 = TMR1 register did not overflow

CMIF
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 (INTCON<7>). User
software should ensure the appropriate
interrupt flag bits are clear prior to enabling
an interrupt.
