PIC32MX5XX/6XX/7XX
26.0 COMPARATOR
The Comparator module contains two comparators that
can be configured in a variety of ways.
Key features of the Comparator module include:
• 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
illustrated in Figure 26-1.

Note 1: On devices with a USB module, and when the module is enabled, this pin is controlled by the USB module,
and therefore, is not available as a comparator input.
2: Internally connected. See Section 27.0 “Comparator Voltage Reference (CV
REF )”.
