this data sheet for device-specific register
and bit information.
This input/output is not available as a selection when configured as an Op amp (OPMODE (CMxCON<10>) = 1).
This module can be configured either as an Op amp or a Comparator using the OPMODE bit.
When configured as an Op amp (OPMODE = 1), the ADC samples the Op amp output; otherwise, the ADC
samples the ANx pin.

The dsPIC33EPXXXGP50X, dsPIC33EPXXXMC20X/
50X, and PIC24EPXXXGP/MC20X devices contain up
to four comparators which can be configured in various
ways. Comparators CMP1, CMP2, and CMP3 also
have the option to be configured as Op amps, with the
output being brought to an external pin for gain/filtering
connections.
comparator options are specified by the Comparator
module’s Special Function Register (SFR) control bits.
These options allow users to:
• Select the edge for trigger and interrupt generation
• Configure the comparator voltage reference
• Configure output blanking and masking
• Configure as a Comparator or Op amp
OPMODE (CMxCON<10>)
(CMP1, CMP2, and CMP3 only)
