Note 1: The Analog-to-Digital conversion result never decreases with an increase in the input voltage and has no
missing codes.
2: Overall functional device operation at V
BOR < VDD < VDDMIN is ensured but not characterized. All device
analog modules, such as the ADC, etc., will function but with degraded performance below V
DDMIN.
