OSCFIF:
Oscillator Fail Interrupt Flag bit
1
= Device oscillator failed, clock input has changed to HFINTOSC (must be cleared by software)
0
= Device clock operating
C1IF:
Comparator C1 Interrupt Flag bit
1
= Comparator C1 output has changed (must be cleared by software)
0
= Comparator C1 output has not changed
C2IF:
Comparator C2 Interrupt Flag bit
1
= Comparator C2 output has changed (must be cleared by software)
0
= Comparator C2 output has not changed
EEIF:
Data EEPROM/Flash Write Operation Interrupt Flag bit
1
= The write operation is complete (must be cleared by software)
0
= The write operation is not complete or has not been started
BCLIF:
Bus Collision Interrupt Flag bit
1
= A bus collision occurred (must be cleared by software)
0
= No bus collision occurred
HLVDIF:
Low-Voltage Detect Interrupt Flag bit
1
= A low-voltage condition occurred (direction determined by the VDIRMAG bit of the
HLVDCON register)
0
= A low-voltage condition has not occurred
TMR3IF:
TMR3 Overflow Interrupt Flag bit
1
= TMR3 register overflowed (must be cleared by software)
0
= TMR3 register did not overflow
CCP2IF:
CCP2 Interrupt Flag bit
Capture mode:
1
