23.0
The analog comparator module contains three compar-
ators that can be independently configured in a variety of
ways. The inputs can be selected from the analog inputs
and two internal voltage references. The digital outputs
are available at the pin level and can also be read
through the control register. Multiple output and interrupt
event generation is also available. Figure 23-1 provides
a generic single comparator from the module.
Key features of the module are:
• Independent comparator control
• Programmable input configuration
• Output to both pin and register levels
• Programmable output polarity
• Independent interrupt generation for each

The CMxCON registers (Register 23-1) select the input
and output configuration for each comparator, as well
as the settings for interrupt generation.
The CMSTAT register (Register 23-2) provides the out-
put results of the comparators. The bits in this register
are read-only.
