Operation Content
This decodes the command and, if it is an unsupported
command, specifies INVALID FIELD IN CDB for the returned
value of the REQUEST SENSE command. It then prepares to
transport the data.
If the host PC has requested data using bulk-in transport, this
sends the same volume of data (H'00) as that requested by
the host PC.
If the host PC has sent data using bulk-out transport, the
number of bytes received are counted.
If there is no data transport, no operation is carried out.
This sends a command fail (CSW status H'01) to the host PC.
