22.0
The analog comparator module contains two compara-
tors that can be configured in a variety of ways. The
inputs can be selected from the analog inputs multiplexed
with pins RA0 through RA5, as well as the on-chip volt-
age reference (see Section 23.0 “Comparator Voltage
Reference Module”). The digital outputs (normal or
inverted) are available at the pin level and can also be
read through the control register.
