OSFIF
PIR2 REGISTER
OSFIF: Oscillator Fail Interrupt Flag
1 = System oscillator failed, clock input has changed to INTOSC (must be cleared in software)
0 = No oscillator failure has been detected
C2IF: Comparator C2 Interrupt Flag
1 = An enabled edge was detected on Comparator C2 (must be cleared in software)
0 = No enabled edge was detected on Comparator C2
C1IF: Comparator C1 Interrupt Flag
1 = An enabled edge was detected on Comparator C1 (must be cleared in software)
0 = No enabled edge was detected on Comparator C1
EEIF: EEPROM Write Completion Interrupt Flag bit
1 = The EEPROM Write operation has completed (must be cleared in software)
0 = The EEPROM Write operation has not completed or has not been started
BCLIF: MSSP Bus Collision Interrupt Flag bit
1 = A Bus Collision was detected (must be cleared in software)
0 = No Bus collision was detected
LCDIF: LCD Module Interrupt Flag bit
1 = The LCD module has completed displaying a frame (must be cleared in software).
0 = The LCD module has not completed displaying a frame
Unimplemented: Read as ‘0’
CCP2IF: CCP2 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)

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
appropriate interrupt flag bits are clear prior
to enabling an interrupt.
