Brown-out Detection
ATmega16/32/64/M1/C1 has an On-chip Brown-out Detection (BOD) circuit for monitoring the
V
can be selected by the BODLEVEL Fuses. The trigger level has a hysteresis to ensure spike
free Brown-out Detection. The hysteresis on the detection level should be interpreted as V

where this is the case, the device is tested down to V
This guarantees that a Brown-Out Reset will occur before V
rect operation of the microcontroller is no longer guaranteed. The test is performed using
BODLEVEL = 010 for Low Operating Voltage and BODLEVEL = 101 for High Operating
Voltage .
