Note 1: Device is functional at VBORMIN < VDD < VDDMIN. Analog modules: ADC, Comparator and DAC will have
degraded performance. Device functionality is tested but not characterized. Refer to Parameter BO10 in
Table 32-11 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.
