7.6.2 Auxiliary Voltage Detector (AVD)
The Voltage Detector function (AVD) is based on
an analog comparison between a V
V
ply voltage (V
for falling voltage is lower than the V
ence value for rising voltage in order to avoid par-
asitic detection (hysteresis).
The output of the AVD comparator is directly read-
able by the application software through a real
time status bit (AVDF) in the SICSR register. This
bit is read only.
Caution: The AVD functions only if the LVD is en-

7.6.2.1 Monitoring the V
The AVD voltage threshold value is relative to the
selected LVD threshold configured by option byte
(see
If the AVD interrupt is enabled, an interrupt is gen-
erated when the voltage crosses the V
V
In the case of a drop in voltage, the AVD interrupt
acts as an early warning, allowing software to shut
down safely before the LVD resets the microcon-
troller. See
