FIGURE 20-1:
20.2
The full range of voltage reference cannot be realized
due to the construction of the module. The transistors
on the top and bottom of the resistor ladder network
(Figure 20-1) keep CV
ence source rails. The voltage reference is derived
from the reference source; therefore, the CV
changes with fluctuations in that source. The tested
absolute accuracy of the voltage reference can be
found in Section 25.0 “Electrical Characteristics”.
20.3
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.

clearing bit CVREN (CVRCON<7>). This Reset also
disconnects the reference from the RA2 pin by clearing
20.4
A device Reset disables the voltage reference by
bit CVROE (CVRCON<6>) and selects the high-voltage
range by clearing bit CVRR (CVRCON<5>). The CVR
value select bits are also cleared.
20.5
The voltage reference module operates independently
of the comparator module. The output of the reference
generator may be connected to the RA2 pin if the
CVROE bit is set. Enabling the voltage reference out-
put onto RA2 when it is configured as a digital input will
increase current consumption. Connecting RA2 as a
digital output with CVRSS enabled will also increase
current consumption.
The RA2 pin can be used as a simple D/A output with
limited drive capability. Due to the limited current drive
capability, a buffer must be used on the voltage
reference output for external connections to V
Figure 20-2 shows an example buffering technique.
