CCON.STOP = 1
SCON.OPEN = 0

and CCON.STOP = 1
When switching between record select operating mode and direct operating mode, disable
operation" is not necessary. This can be used to optimize the control function.

SCON.OPEN = 0
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
[m]
mode.

Bit B7 = CCON.OPM2

CCON.OPM1 = SCON.OPM1
AND
CCON.OPM2 = SCON.OPM2
If necessary: Reenable operation

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.
This action is mandatory.

This action is a recommendation.
