Comparator Response Time
Comparator Outputs
Response time is the minimum time, after selecting a new reference voltage or input source,
before the comparator output is guaranteed to have a valid level. If the internal reference is
changed, the maximum settling time of the internal voltage reference must be considered when
using the comparator outputs. Otherwise the maximum response time of the comparators should
be used.
The comparator outputs are read through the CMCON register. These bits are read only. The
comparator outputs may also be directly output to the I/O pins. When CM2:CM0 = 110, multiplex-
ors in the output path of the I/O 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.
ator output block diagram.
The TRIS bits will still function as the output enable/disable for the I/O pins while in this mode.
