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’

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.
