The comparator voltage reference module provides an
internally
comparators. The following features are available:
• Independent from Comparator operation
• Two 16-level voltage ranges
• Output clamped to V
• Ratiometric with V
• Fixed Reference (0.6V)
The VRCON register (Register 8-6) controls the
voltage reference module shown in Figure 8-9.
8.11.1
The comparator voltage reference is independent of
the comparator configuration. Setting the FVREN bit of
the VRCON register will enable the voltage reference.
8.11.2
The
voltage levels in each range. Range selection is
controlled by the VRR bit of the VRCON register. The
16 levels are set with the VR<3:0> bits of the VRCON
register.

The fixed voltage reference output voltage can be set
to Vss with no power consumption by clearing the
FVREN bit of the VRCON register (FVREN = 0). This
allows the comparator to detect a zero-crossing while
not consuming additional module current.
