(3)
Counter value
=

→
comparison bit
is set and

activated
(4)
Comparison bit
is reset for leaving
hysteresis
range and

(5)
Counter value
=

(6)
Counter value

active
→

remains set
(7) Leave

≥
comparison value
→
comparison bit
is reset
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.
