VR310 T
SET Settling Time — 1 10 s (Note 1)
Note 1: Settling time is measured while CVRR = 1 and CVR<3:0> bits transition from ‘0000’ to ‘1111’.
2: Device is functional at VBORMIN < VDD < VDDMIN, but will have degraded performance. Device functionality
is tested, but not characterized. Analog modules (ADC, op amp/comparator and comparator voltage
reference) may have degraded performance. Refer to Parameter BO10 in Table 30-13 for the minimum
and maximum BOR values.
