bit 1
Unimplemented: Read as ‘0’
bit 0
CCP2IF: CCP2 Interrupt Flag bit
1 = Interrupt is pending
0 = Interrupt is not pending
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 software should ensure the
appropriate interrupt flag bits are clear prior
to enabling an interrupt.
