Legend:
R = Readable bit
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
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 5-4
Unimplemented: Read as ‘0’
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
LVDIF: Low-Voltage Detect Interrupt Flag bit
1
= A low-voltage condition occurred (must be cleared in software)
0
= The device voltage is above the regulator’s low-voltage trip point
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
Unimplemented: Read as ‘0’
