PIR2 Register
PIR2 – PERIPHERAL INTERRUPT REQUEST REGISTER 2 (ADDRESS: 0Dh)
OSFIF: Oscillator Fail Interrupt Flag bit
1 = System oscillator failed, clock input has changed to INTOSC (must be cleared in software)
0 = System clock operating
C2IF: Comparator 2 Interrupt Flag bit
1 = Comparator output (C2OUT bit) has changed (must be cleared in software)
0 = Comparator output (C2OUT bit) has not changed
C1IF: Comparator 1 Interrupt Flag bit
1 = Comparator output (C1OUT bit) has changed (must be cleared in software)
0 = Comparator output (C1OUT bit) has not changed
LCDIF: LCD Module Interrupt bit
1 = LCD has generated an interrupt
0 = LCD has not generated an interrupt
Unimplemented: Read as ‘0’
LVDIF: Low Voltage Detect Interrupt Flag bit
1 = LVD has generated an interrupt
0 = LVD has not generated an interrupt
Unimplemented: Read as ‘0’
CCP2IF: CCP2 Interrupt Flag bit (only available in 16F914/917)

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.
