Note 1: The Analog-to-Digital conversion result never decreases with an increase in input voltage and has no missing codes.
2: Overall functional device operation at V
BORMIN < VDD < VDDMIN is tested but not characterized. All device analog
modules, such as the ADC, etc., will function, but with degraded performance below V
DDMIN. Refer to
Parameter BO10 in Table 25-11 for BOR values.
3: These parameters are characterized by similarity, but are not tested in manufacturing.
