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 are also available. A generic
single comparator from the module is shown in
Figure 24-1.
Key features of the module includes:
• Independent comparator control
• Programmable input configuration
• Output to both pin and register levels
• Programmable output polarity
• Independent interrupt generation for each

Comparators, 1 and 3, use C2INB as an input to the inverting terminal. Comparator 2 uses C2IND as an input to
the inverted terminal.
C1INC, C2INC and C2IND are all unavailable on 64-pin devices (PIC18F6XK90).

The CMxCON registers (CM1CON, CM2CON and
CM3CON) select the input and output configuration for
each comparator, as well as the settings for interrupt
generation (see Register 24-1).
The CMSTAT register (Register 24-2) provides the out-
put results of the comparators. The bits in this register
are read-only.
