Comparator Configuration

There are eight modes of operation for the comparator.

The CM<2:0> bits of the CMCON0 register are used to

select these modes as shown in Figure 7-5. I/O lines

change as a function of the mode and are designated

as follows:

• Analog function (A): digital input buffer is disabled

• Digital function (D): comparator digital output,

overrides port function

• Normal port function (I/O): independent of

comparator

The port pins denoted as “A” will read as a ‘0’

regardless of the state of the I/O pin or the I/O control

TRIS bit. Pins used as analog inputs should also have

the corresponding TRIS bit set to ‘1’ to disable the

digital output driver. Pins denoted as “D” should have

the corresponding TRIS bit set to ‘0’ to enable the

digital output driver.

Note:

Comparator interrupts should be disabled

during a Comparator mode change to

prevent unintended interrupts.
