this is the case, the device is tested down to Vcc = V
antees that a Brown-Out Reset will occur before Vcc drops to a voltage where correct
operation of the microcontroller is no longer guaranteed. The test is performed using
BODLEVEL = 101 for Low Operating Voltage and BODLEVEL = 100 for High operating
Voltage.
