bit 7
OSCFIF: Oscillator Fail Interrupt Flag bit
1
= Device oscillator failed, clock input has changed to INTOSC (must be cleared in software)
0
= Device clock operating
bit 6
CMIF: Comparator Interrupt Flag bit
1
= Comparator input has changed (must be cleared in software)
0
= Comparator input has not changed
bit 5
Unimplemented: Read as ‘0’
bit 4
EEIF: Data EEPROM/Flash Write Operation Interrupt Flag bit
1
= The write operation is complete (must be cleared in software)
0
= The write operation is not complete or has not been started
bit 3
BCLIF: Bus Collision Interrupt Flag bit
1
= A bus collision occurred (must be cleared in software)
0
= No bus collision occurred
bit 2
HLVDIF: High/Low-Voltage Detect Interrupt Flag bit
1
= A high/low-voltage condition occurred (direction determined by
VDIRMAG bit, HLVDCON<7>)
0
= A high/low-voltage condition has not occurred
bit 1
TMR3IF: TMR3 Overflow Interrupt Flag bit
1
= TMR3 register overflowed (must be cleared in software)
0
= TMR3 register did not overflow
bit 0
CCP2IF: CCPx 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.
Legend:
R = Readable bit
W = Writable bit
U = Unimplemented bit, read as ‘0’
-n = Value at POR
‘1’ = Bit is set
‘0’ = Bit is cleared
x = Bit is unknown
