Comparator Outputs
The comparator outputs are read through the CMCON
register. These bits are read only. The comparator
outputs may also be directly output to the RA3 and RA4
I/O pins. When the CM<2:0> = 110 or 001, multiplexors
in the output path of the RA3 and RA4/T0CK1 pins will
switch and the output of each pin will be the unsynchro-
nized output of the comparator. The uncertainty of each
of the comparators is related to the input offset voltage
and the response time given in the specifications.
Figure 10-3 shows the comparator output block
diagram.
The TRISA bits will still function as an output enable/
disable for the RA3 and RA4/T0CK1 pins while in this
mode.

MODIFIED COMPARATOR OUTPUT BLOCK DIAGRAM
Note 1:
When reading the PORT register, all pins
configured as analog inputs will read as a
‘0’. Pins configured as digital inputs will
convert an analog input, according to the
Schmitt Trigger input specification.
2:
Analog levels on any pin that is defined as
a digital input may cause the input buffer
to consume more current than is
specified.
