Each comparator has built-in hysteresis that is user
enabled by setting the C1HYS or C2HYS bits of the
CM2CON1 register. The hysteresis feature can help
filter noise and reduce multiple comparator output
transitions when the output is changing state.

Figure 8-9 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
