8.4
Response time is the minimum time, after selecting a
new reference voltage or input source, before the
comparator output has a valid level. If the internal refer-
ence is changed, the maximum delay of the internal
voltage reference must be considered when using the
comparator outputs, otherwise the maximum delay of
the comparators should be used (Table 13-1 ).

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, multiplexors in the
output path of the RA3 and RA4 pins will switch and the
output of each pin will be the unsynchronized 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 8-3 shows the comparator output block diagram.
The TRISA bits will still function as an output
enable/disable for the RA3 and RA4 pins while in this
mode.
