The
hysteresis
serves e.g. the avoidance of many toggle processes of the
interrupt, if the
counter value
is in the range of the
comparison value
. You
may set a range of 0 to 255. The settings 0 and 1 deactivate the
hysteresis
.
The
hysteresis
influences the zero run, over-/underflow and
comparison
value
.
An activated
hysteresis
remains active after a change. The new
hysteresis
range is taken over at the next hysteresis event.
The following pictures illustrate the behavior of the comparison bit for
hysteresis
0 and
hysteresis
3 for the according conditions:

(1)
Counter value
≥
comparison value
→
comparison bit
is set and
hysteresis
activated
(2) Leave
hysteresis
range
→
comparison bit
is reset
(3)
Counter value
≥
comparison value
→
comparison bit
is set and
hysteresis
activated
(4) Leave
hysteresis
range,
comparison bit
remains set for
counter value
≥
comparison value
(5)
Counter value
<
comparison value
and
hysteresis
active
→
comparison bit
is reset
(6)
Counter value
≥
comparison value
→
comparison bit
is not set for
hysteresis
active
(7) Leave
hysteresis
range,
comparison bit
remains set for
counter value
≥
comparison value
With reaching the comparison condition the
hysteresis
gets active. At active
hysteresis
the comparison result remains unchanged until the
counter value
leaves the set
hysteresis
range. After leaving the
hysteresis
range a new
hysteresis
is only activated with again reaching the comparison conditions.
