may be below nominal minimum operating voltage for some devices. For devices where
BOT
this is the case, the device is tested down to V
antees that a Brown-out Reset will occur before V
operation of the microcontroller is no longer guaranteed. The test is performed using
BODLEVEL = 1 and BODLEVEL = 0 for ATmega16A.
