8.11
Each comparator has built-in hysteresis that is user
enabled by setting the CMHYS bit of the CMCON1 reg-
ister. The hysteresis feature can help filter noise and
reduce multiple comparator output transitions when the
output is changing state.

Figure 8-7 shows the relationship between the analog
input levels and digital output of a comparator with and
without hysteresis. The output of the comparator
changes from a low state to a high state only when the
