This command performs setting and changing of each type of parameter related to disk drive
physical attributes, data format, timing of SCSI bus disconnect/reconnect processing and error
recovery procedures, etc.
This command's function is the same as that of the Group 0 MODE SELECT command (item
3.1.5), except that the format of its data transferred by the INIT differs partially from that of
the (MODE SELECT) data format.
Fig. 3.16 shows the configuration of the parameter list (MODE SELECT parameters)
transferred by this command from the INIT. Compared to the 4-byte header in the Group 0
MODE SELECT command, it is necessary for an 8-byte header to be transferred in this
command. The contents of each field in the header except that the byte positions differ, are
the same as in the case of the Group 0 MODE SELECT command. The contents of the other
parameters (Block descriptor, Page descriptor) are also the same as in the case of the Group 0
MODE SELECT command.
