21.0
The
comparators that can be configured in a variety of
ways. The inputs can be selected from the analog
inputs multiplexed with pins RF1 through RF6, as well
as the on-chip voltage reference (see Section 22.0
“Comparator Voltage Reference Module”). The digi-
tal outputs (normal or inverted) are available at the pin
level and can also be read through the control register.
