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
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

’0’ = Bit is cleared
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.
