The "Transfer byte length" field in the CDB specifies the defect data length
(number of bytes) that can be received by the INIT. The IDD terminates data
transfer when transfer of the length of defect data specified in the "Transfer byte
length" field is completed or when transfer of all the defect data of the specified
type is completed. Also, when zero is specified in the "Transfer byte length"
field, this command is terminated without execution of data transfer.
Table 4.105 lists the format of defect data transferred to the INIT by this
command.
