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.
This field contains information about the CDB for the Operation Code being queried. Note that
CDB Usage Data 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. Refer to Table 5-36 for a list
of the data returned for each of the OpCode values that can be sent in the INQUIRY command.
