These parameters are characterized but not tested.
Response time measured with one comparator input at V
from V
Comparator Hysteresis is available when the CxHYS bit of the CMxCON0 register is enabled.
High power only.
Settling time measured while DACR<4:0> transitions from ‘0000’ to ‘1111’.
These parameters are characterized but not tested.
