Note 1: These parameters are not characterized or tested in manufacturing.
2: The voltage difference between AV
DD and VDD cannot exceed 300 mV at any time during operation or
start-up.
3: Device is functional at V
BORMIN < 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.
