tested down to V
a voltage where correct operation of the microcontroller is no longer guaranteed. The test is performed using
BODLEVEL = 110 for 4 MHz operation of ATmega640V/1280V/1281V/2560V/2561V, BODLEVEL = 101 for 8 MHz operation
of ATmega640V/1280V/1281V/2560V/2561V and ATmega640/1280/1281, and BODLEVEL = 100 for 16 MHz operation of
ATmega640/1280/1281/2560/2561.
