CDB Size
This field contains the number of bytes in the CDB for the Operation
Code being requested and the size of the CDB Usage Data in the data
that is returned in response to the INQUIRY.
CDB Usage Data
This field contains information about the CDB for the Operation
Code being queried. Note that the first byte of the CDB Usage Data
contains the OpCode for the operation specified. All of the other
bytes of the CDB Usage Data contain a map for bits in the CDB of the
OpCode specified.
NOTE:
The bits in the map have a 1-to-1 correspondence to the CDB for the OpCode being
queried. That is, if the device senses a bit as the entire field or as part of the field of the
operation, the map in CDB Usage Data contains a 1 in the corresponding bit position. If the
device ignores a bit or declares a bit as “reserved” in the CDB for the OpCode being queried,
the map has a 0 in that corresponding bit position.
