——10μs—
Note 1: Parameters are characterized but not tested.
2: Response time measured with one comparator input at (V
DD - 1.5)/2, while the other input transitions from
V
SS to VDD.
3: 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.
