System and Reset Characteristics
1. Values are guidelines only.
2. The Power-on Reset will not work unless the supply voltage has been below 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 ATmega48P/88P/168PV, and BODLEVEL = 101 and BODLEVEL = 100 for
ATmega48P/88P/168P.
