20.1
There are eight modes of operation for the compara-
tors, shown in Figure 20-1. Bits, CM2:CM0 of the
CMCON register, are used to select these modes. The
TRISA register controls the data direction of the com-
parator pins for each mode. If the Comparator mode is

Two Independent Comparators
CM2:CM0 = 010
Two Common Reference Comparators
CM2:CM0 = 100
One Independent Comparator with Output
CM2:CM0 = 001
A = Analog Input, port reads zeros always
* Setting the TRISA<5:4> bits will disable the comparator outputs by configuring the pins as inputs.
