PIC16F882/883/884/886/887
8.10
The Comparator Voltage Reference module provides
an internally generated voltage reference for the com-
parators. 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 8-5) controls the
Voltage Reference module shown in Figure 8-8.
The voltage source is selectable through both ends of
the 16 connection resistor ladder network. Bit VRSS of
the VRCON register selects either the internal or
external voltage source.
The PIC16F883/884/886/887 allows the CV
to be output to the RA2 pin of PORTA under certain
configurations only. For more details, see Figure 8-9.
8.10.1
The comparator voltage reference is independent of
the comparator configuration. Setting the VREN bit of
the VRCON register will enable the voltage reference.
8.10.2
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.

Preliminary
8.10.3
The CV
power consumption by configuring VRCON as follows:
• VREN = 0
• VRR = 1
• VR<3:0> = 0000
This allows the comparator to detect a zero-crossing
while not consuming additional CV
8.10.4
The comparator voltage reference is V
therefore, the CV
V
Voltage Reference can be found in Section 17.0
“Electrical Specifications”.
8.10.5
The fixed voltage reference is independent of V
a nominal output voltage of 0.6V. This reference can be
enabled by setting the FVREN bit of the SRCON
register to ‘1’. This reference is always enabled when
the HFINTOSC oscillator is active.
8.10.6
When the fixed Voltage Reference module is enabled,
it will require some time for the reference and its
amplifier circuits to stabilize. The user program must
include a small delay routine to allow the module to
settle. See the electrical specifications section for the
minimum delay requirement.
8.10.7
Multiplexers on the output of the Voltage Reference
module enable selection of either the CV
voltage reference for use by the comparators.
Setting the C1VREN bit of the VRCON register enables
current to flow in the CV
the CV
bit selects the fixed voltage for use by C1.
Setting the C2VREN bit of the VRCON register enables
current to flow in the CV
the CV
bit selects the fixed voltage for use by C2.
When both the C1VREN and C2VREN bits are cleared,
current flow in the CV
minimizing the power drain of the voltage reference
peripheral.
