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/CMP2
pins will switch and the output of each pin will be the
unsynchronized
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/AN3/CMP1 and RA4/T0CK1/
CMP2 pins while in this mode.
