12.1.2
The CM2CON0 register is a functional copy of the
CM1CON0 register described in Section 12.1.1. A sec-
ond control register, CM2CON1, is also present for
control of an additional synchronizing feature, as well
as mirrors of both comparator outputs.
12.1.2.1
The CM2CON0 register, shown in Register 12-2, con-
tains the control and status bits for Comparator C2.
Setting C2ON (CM2CON0<7>) enables Comparator
C2 for operation.
Bits C2CH<1:0> (CM2CON0<1:0>) select the compar-
ator input from the four analog pins, AN<7:4>.
C2R (CM2CON0<2>) selects the reference to be used
with the comparator. Setting C2R (CM2CON0<2>)
selects the output of the DAC module as the reference
for the comparator. Clearing C2R selects the V
input on the RA2/AN2/V

The output of the comparator is available internally via
the C2OUT bit (CM2CON0<6>). To make the output
available for an external connection, the C2OE bit
(CM2CON0<5>) must be set.
The comparator output, C2OUT, can be inverted by
setting the C2POL bit (CM2CON0<4>). Clearing
C2POL results in a non-inverted output. A complete
table showing the output state versus input conditions
and the polarity bit is shown in Table 12-3.
C2SP (CM2CON0<3>) configures the speed of the
comparator. When C2SP is set, the comparator oper-
ates at its normal speed. Clearing C2SP operates the
comparator in low power mode.

output is not required for the C2 interrupt.
