Note 1: Device is functional at V
BORMIN < VDD < VDDMIN, but will have degraded performance. Device functionality
is tested, but not characterized. Analog modules: ADC, op amp/comparator and comparator voltage
reference, will have degraded performance. Refer to Parameter BO10 in Table 33-12 for the minimum and
maximum BOR values.
2: For all accuracy specifications, VINL = AVSS = VREFL = 0V and AVDD = VREFH = 3.6V.
