3-8-4 Hysteresis Setting
The hysteresis of the threshold values (hysteresis width) can be set. Any
value can be input directly or the hysteresis can be set automatically.
Refer to 4-5-6 FUN Mode Status Transitions.
If the hysteresis cannot be set, refer to 5-2-4 Unable to Set
Hysteresis.
When the hysteresis is set automatically, the hysteresis width is almost
equal to the resolution.
