10: Negative Hysteresis = 10 mV.
11: Negative Hysteresis = 20 mV.
Upon enabling a comparator, the output of the comparator is not immediately valid. Before
using a comparator as an interrupt or reset source, software should wait for a minimum of
the specified “Power-up time” as specified in Table 12.1, “Comparator Electrical Characteris-
tics,” on page 122.
