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 13-2
).
8.5
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 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 8-4 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 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.
