System and Reset Characteristics
1. The Power-on Reset will not work unless the supply voltage has been below V
1. V

tested down to V
a voltage where correct operation of the microcontroller is no longer guaranteed. The test is performed using
BODLEVEL = 110 and BODLEVEL = 101 for ATmega48V/88V/168V, and BODLEVEL = 101 and BODLEVEL = 100 for
ATmega48/88/168.
