PIC32MX1XX/2XX
22.0 COMPARATOR
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
(IV
REF)
- Comparator voltage reference (CV
REF)
• Outputs can be Inverted
• Selectable interrupt generation
A block diagram of the comparator module is provided
in Figure 22-1.
