Reset and the Voltage Reference
Brown-out Detection
Figure 11-4. Watchdog Reset During Operation
ATmega16HVB/32HVB has an On-chip Brown-out Detection (BOD) circuit for monitoring the
V
hysteresis to ensure spike free Brown-out Detection. The hysteresis on the detection level
should be interpreted as V
The BOD is automatically enabled in all modes of operation, except in Power-off mode.
When the BOD is enabled, and V

Figure 11-5. Brown-out Reset During Operation
The Voltage Reference is important for the performance of the system as the VREF voltage will
be used as reference voltage for several modules. It is therefore important to notice that after a
reset condition the Voltage Reference needs calibration and settling before the VREF voltage is
accurate. For details on Voltage Reference calibration and settling time, See
and Temperature Sensor” on page
