2. The Power-on Reset will not work unless the supply voltage has been below V
1. 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 = 10 for ATmega329P/3290PV and BODLEVEL = 01 for ATmega329P/3290P.
