Note 1: The Analog-to-Digital conversion result never decreases with an increase in the input voltage and has no
missing codes.
2: These parameters are characterized by similarity, but are not tested in manufacturing.
3: These parameters are characterized, but are tested at 20 ksps only.
4: Overall functional device operation at V
BOR < VDD < VDDMIN is guaranteed but not characterized. All
device analog modules such as the ADC, etc., will function but with degraded performance below VDDMIN
