22.0
The
comparators that can be configured in a variety of
ways. The inputs can be selected from the analog
inputs multiplexed with pins RF3 through RF6, as well
as the on-chip voltage reference (see Section 23.0
“Comparator Voltage Reference Module”). The
digital outputs (normal or inverted) are available on
RF1 and RF2 and can also be read through the control
register.
