With reaching the comparison condition the
hysteresis
gets active. At active
hysteresis
the comparison result remains unchanged until the
counter value
leaves the set
hyste-
resis
range. After leaving the
hysteresis
range a new
hysteresis
is only activated with
again reaching the comparison conditions.
