Write Single Block
When receiving the Write Single Block command, the LRI64 writes the requested block with
the data contained in the request and report the success of the operation in the response.
The Option_Flag is not supported and must be set to 0. The Write Single Block can be
issued in both addressed and non addressed modes.
During the write cycle t
