The R/W head makes exactly one attempt to write a word to the configuration
range ("Protection Word" or "Control Word") from the address <ConfAddr>.
The password mode must be active so that the R/W head can write to the
configuration range.
If the password mode is deactivated, every data word outside of the write-
protected range can be written to. If you would like to modify the write-protected
range, you must modify the "Protection Word" accordingly.
For example:
With the R/W head on channel 1, one data word (4 bytes) that does not contain
details of the address and data length should be transferred during each read
command (accessed with 00 byte and address 0000). Password mode must be
activated beforehand by transmitting the command Set password mode.
Bit no.
