21.0
There are two independent voltage references
available:
• Programmable Comparator Voltage Reference
• 1.2V Fixed Voltage Reference
21.1
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
• 1.2 Fixed Reference Voltage (FVR)
The CVRCON register (Register 21-1) controls the
Voltage Reference module shown in Figure 21-1.
21.1.1
The comparator voltage reference is independent of
the comparator configuration. Setting the CVREN bit of
the CVRCON register will enable the voltage reference
by allowing current to flow in the CV
When both the CVREN bit is cleared, current flow in the
CV
drain of the voltage reference peripheral.
21.1.2
The
voltage levels in each range. Range selection is
controlled by the CVRR bit of the CVRCON register.
The 16 levels are set with the CVR<3:0> bits of the
CVRCON register.

The CV
power consumption by configuring CVRCON as
follows:
• CVREN = 0
• CVRR = 1
• CVR<3:0> = 0000
This allows the comparator to detect a zero-crossing
while not consuming additional CV
21.1.4
The comparator voltage reference is V
therefore, the CV
V
Voltage Reference can be found in Section 26.0
“Electrical Characteristics”.
21.1.5
The CV
device CV
CON register to ‘1’. Selecting the reference voltage for
output on the CV
digital output buffer and digital input threshold detector
functions of that pin. Reading the CV
has been configured for reference voltage output will
always return a ‘0’.
Due to the limited current drive capability, a buffer must
be used on the voltage reference output for external
connections to CV
buffering technique.
21.1.6
When the device wakes up from Sleep through an
interrupt or a Watchdog Timer time-out, the contents of
the CVRCON register are not affected. To minimize
current consumption in Sleep mode, the voltage
reference should be disabled.
21.1.7
A device Reset affects the following:
• Comparator voltage reference is disabled
• Fixed voltage reference is disabled
• CV
• The high-voltage range is selected
• The CVR<3:0> range select bits are cleared
