The PIR2 register contains the flag bits for the CCP2
interrupt, the SSP bus collision interrupt, EEPROM
write operation interrupt and the comparator interrupt.

PIR2 Register
PIR2 REGISTER (ADDRESS 0Dh)
Unimplemented: Read as ‘0’
CMIF: Comparator Interrupt Flag bit
1 = The comparator input has changed (must be cleared in software)
0 = The comparator input has not changed
Unimplemented: Read as ‘0’
EEIF: EEPROM Write Operation Interrupt Flag bit
1 = The write operation completed (must be cleared in software)
0 = The write operation is not complete or has not been started
BCLIF: Bus Collision Interrupt Flag bit
1 = A bus collision has occurred in the SSP when configured for I
0 = No bus collision has occurred
Unimplemented: Read as ‘0’
CCP2IF: CCP2 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.

BCLIF
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 (INTCON<7>). User
software should ensure the appropriate
interrupt flag bits are clear prior to
enabling an interrupt.
