TMR3IF: TMR3 Overflow Interrupt Flag bit
1= TMR3 register overflowed (must be cleared in software)
0= TMR3 register did not overflow
CCP2IF: CCP2 Interrupt Flag bit
Capture mode:
1= A TMR1 or TMR3 register capture occurred (must be cleared in software)
0= No TMR1 or TMR3 register capture occurred
Compare mode:

0= No TMR1 or TMR3 register compare match occurred
PWM mode:
Unused in this mode
Legend:
R = Readable bit
- n = Value at POR
W = Writable bit
‘1’ = Bit is set
U = Unimplemented bit, read as ‘0’
‘0’ = Bit is cleared x = Bit is unknown
