Sub-Index 0:
The entry at sub-index 0 contains the largest Sub-Index that is
supported. Value = 4.
Sub-
Index 1…4:
Contains the save command.
By read access the device provides information about its saving capability.
Bit 0 = 1, the device saves parameters only on command. That means, if parameters
have been changed by the user and no "Store Parameter Command" had been
executed, at the next power on , the parameters will have their old values.

In order to avoid storage of parameters by mistake, storage is only executed when a
specific signature is written to the appropriate sub-index. The signature is "save".

On reception of the correct signature, the device saves the parameters. If saving
failed, the device responds with abort domain transfer: Error code 0606 0000h.
If a wrong signature is written, the device refuses to save and responds with abort
domain transfer: Error code 0800 0020h.
