devices where this is the case, the device is tested down to V
production test. This guarantees that a Brown-out Reset will occur before V
to a voltage where correct operation of the microcontroller is no longer guaranteed.
The test is performed using BODLEVEL=1 for ATmega8515L and BODLEVEL=0 for
ATmega8515. BODLEVEL=1 is not applicable for ATmega8515.
