. Analog modules: ADC, Comparator and DAC will have
degraded performance. Device functionality is tested but not characterized. Refer to Parameter
for the minimum and maximum BOR values.
2: The Analog-to-Digital conversion result never decreases with an increase in input voltage and has no
missing codes.
