EEIF
PIR1 Register
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 Interrupt Flag bit
1 = A/D conversion complete
0 = A/D conversion has not completed or has not been started
CCP1IF: CCP1 Interrupt Flag bit
Capture mode:
1 = A TMR1 register capture occurred (must be cleared in software)
0 = No TMR1 register capture occurred
Compare mode:
1 = A TMR1 register compare match occurred (must be cleared in software)
0 = No TMR1 register compare match occurred
PWM mode:
Unused in this mode
C2IF: Comparator 2 Interrupt Flag bit
1 = Comparator 2 output has changed (must be cleared in software)
0 = Comparator 2 output has not changed
C1IF: Comparator 1 Interrupt Flag bit
1 = Comparator 1 output has changed (must be cleared in software)
0 = Comparator 1 output has not changed
OSFIF: Oscillator Fail Interrupt Flag bit
1 = System oscillator failed, clock input has changed to INTOSC (must be cleared in software)
0 = System clock operating
TMR2IF: Timer2 to PR2 Match Interrupt Flag bit
1 = Timer2 to PR2 match occurred (must be cleared in software)
0 = Timer2 to PR2 match has not occurred
TMR1IF: Timer1 Overflow Interrupt Flag bit
1 = Timer1 register overflowed (must be cleared in software)
0 = Timer1 has not overflowed

Note:
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 of the INTCON register. User
software should ensure the appropriate
interrupt flag bits are clear prior to enabling
an interrupt.
