tested absolute accuracy of the Voltage Reference can
be found in Table 17-2.

When the device wakes-up from SLEEP through an
interrupt or a Watchdog Timer timeout, the contents of
the VRCON register are not affected. To minimize
current consumption in SLEEP mode, the Voltage
Reference should be disabled.

of the reference generator may be connected to the
RA2 pin if the TRISA<2> bit is set and the V
VRCON<6>, is set. Enabling the Voltage Reference
output onto the RA2 pin with an input signal present will
increase current consumption. Connecting RA2 as a
digital output with V
current consumption.
The RA2 pin can be used as a simple D/A output with
limited drive capability. Due to the limited drive
capability, a buffer must be used in conjunction with the
Voltage Reference output for external connections to
