DATASHEET
4.4.3 Device ID Strings
These bytes are used to specify the LUN descriptor returned by the device. These bytes are used in
combination with the device to LUN mapping bytes in applications where the LUNs need to be
reordered and renamed. If multiple devices are mapped to the same LUN (a COMBO LUN), then the
CLUN#_ID_STR will be used to name the COMBO LUN instead of the individual device strings. When
applicable, the
SM value will be overridden with xD once an xD-Picture Card has been identified.
