PIE1 REGISTER
PIR1 REGISTER
Interrupt flag bits get 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.
Unimplemented: Read as '0'
CMIE: Comparator Interrupt Enable bit
1 = Enables the Comparator interrupt
Unimplemented: Read as'0'
CMIF: Comparator Interrupt Flag bit
1 = Comparator input has changed
0 = Comparator input has not changed
0 = Disables the Comparator interrupt
