22.0 COMPARATOR

Note 1: This data sheet summarizes the features

of the PIC32MX1XX/2XX family of

devices. It is not intended to be a

comprehensive reference source. To

complement the information in this

data sheet, refer to Section 19.

“Comparator” (DS61110) in the “PIC32

Family Reference Manual”, which is

available from the Microchip web site

(www.microchip.com/PIC32).

2: Some registers and associated bits

described in this section may not be

available on all devices. Refer to

Section 4.0 “Memory Organization” in

this data sheet for device-specific register

and bit information.

The PIC32MX1XX/2XX Analog Comparator module

contains three comparators that can be configured in a

variety of ways.

Following are some of the key features of this module:

• Selectable inputs available include:

- Analog inputs multiplexed with I/O pins

- On-chip internal absolute voltage reference

(IVREF)

- Comparator voltage reference (CVREF)

• Outputs can be Inverted

• Selectable interrupt generation

A block diagram of the comparator module is provided

in Figure 22-1.
