PIC16F785/HV785
10.0
There are two voltage references available in the
PIC16F785/HV785: The voltage referred to as the
comparator reference (CV
based on V
ence (VR) is a fixed voltage derived from a stable band
gap source. Each source may be individually routed
internally to the comparators or output, buffered or
unbuffered, on the RA1/AN1/C12IN0-/V
pin.
10.1
The comparator module also allows the selection of an
internally generated voltage reference for one of the
comparator inputs. The VRCON register (Register 10-1)
controls the voltage reference module shown in
Figure 10-1.

The voltage reference can output 32 distinct voltage
levels, 16 in a high range and 16 in a low range.
The following equation determines the output voltages:
