1. The Power-on Reset will not work unless the supply voltage has been below V
2. V
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 for ATmega16L and BODLEVEL = 0 for ATmega16. BODLEVEL = 1 is not
applicable for ATmega16.
