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

Figure 9-7 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
