Comparator Response Time
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 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 12-2 and Table 12-3).
7.5
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 CM2:CM0 = 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
specications.
Figure 7-4 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.
Note 1: When reading the PORTA register, all pins
congured as analog inputs will read as a
‘0’. Pins congured as digital inputs will
convert an analog input according to the
Schmitt Trigger input specication.
Note 2: Analog levels on any pin that is dened as
a digital input may cause the input buffer
to consume more current than is speci-
ed.
