The status word is used as a handshake between CMAX and FCT. As soon as the bit 0 is set by the
controller, the data are no longer overwritten. In this way the FCT can consistently read the data.
After reading, FCT writes a 0 into the status word as confirmation, and the controller updates the
values. The status word (index 1) may be written by the FCT without higher−order controller. It is also
not necessary to enter a password.
