register bits 3 and 4.
COMPARATOR OPERATION
The comparator output reflects the relationship between the
analog input to the reference input. If the voltage on the an-
alog input is higher than the voltage on the reference input,
then the comparator output is at a High state. If the voltage
on the analog input is lower than the voltage on the reference
input, then the analog output is at a Low state.
Comparator Definitions

The usable voltage range for the positive input and
reference input is called the Comparator Input Common

When the analog comparator function is enabled, bit 4 of
the input register is defined as holding the synchronized out-
put of the comparator, while bit 3 retains a synchronized
sample of the reference input.
If the interrupts for
special function is selected, the output of the comparator
generates interrupts.
