Wait for feedback from the switch−over. During switch−over the status bytes
2 ... 8 cannot be evaluated, because they cannot be clearly assigned to an
operating mode.
All bytes depending on the operating mode are set to zero. This prevents old target data from
affecting the CMAX even if these have a completely different meaning in the new operating
mode.
Assumed:
CCNON. ENABLE =

and CCON.STOP = 1
This action is mandatory.
This action is a recommendation.
It does not have to be carried out
