Voltage Reference Accuracy/Error
Operation During Sleep
Effects of a Reset
The full range of V

changes with fluctuations in V
in the Device Data Sheets electrical specification
When the device wakes up from sleep through an interrupt or a Watchdog Timer time-out, the
contents of the VRCON register are not affected. To minimize current consumption in SLEEP
mode, the Voltage Reference should be disabled.
A device reset disables the Voltage Reference by clearing the VREN bit (VRCON<7>). This reset
also disconnects the reference from the V
selects the high voltage range by clearing the VRR bit (VRCON<5>). The V
VRCON<3:0>, are also cleared.
