LVDIF: Low Voltage Detect Interrupt Flag bit
1 = The supply voltage has fallen below the specified LVD voltage (must be cleared in software)
0 = The supply voltage is greater than the specified LVD voltage
ADIF: Analog-to-Digital Converter Interrupt Flag bit
1 = An ADC conversion completed (must be cleared in software)
0 = The ADC conversion is not complete
C2IF: Comparator C2 Interrupt Flag bit
1 = Comparator C2 input has crossed the threshold (must be cleared in software)
0 = Comparator C2 input has not crossed the threshold
C1IF: Comparator C1 Interrupt Flag bit
1 = Comparator C1 input has crossed the threshold (must be cleared in software)
0 = Comparator C1 input has not crossed the threshold
Unimplemented: Read as ‘0’
TMR1IF: TMR1 Overflow Interrupt Flag bit
1 = TMR1 register overflowed (must be cleared in software)
0 = TMR1 register did not overflow

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 soft-
ware should ensure the appropriate inter-
rupt flag bits are clear prior to enabling an
interrupt.
