3.1 Control/Sense Commands

Figure 3.9 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.
