When the value specified in the "Page code" field is other than X '3F', the specified "Page
descriptor" only is transferred to the INIT, and when X '3F' is specified, all the "Page descriptors"
supported by the IDD are transferred to the INIT in the ascending order of the page code, but if
SCSI-1/CCS is specified by the CHANGE DEFINITION command (SCSI level), Page code 7, Page
code 8, Page code A, Page code C and Page code 1C are not transferred.
specified in the "Page code field," the "Page descriptor" is not transferred. If page codes other than
the abovementioned ones ("Page descriptors" which are not supported by the IDD) are specified, the
command is terminated with a CHECK CONDITION status (ILLEGAL REQUEST [=5] / Invalid
field in CDB [=24-00]).
Also the "PC (page control)" field in CDB byte 2 specifies the type of parameter value in the "Page
descriptor" transferred to the INIT by this command, as shown in Table 3.1.
Note:
Even in cases where the value specified in the MODE SELECT or MODE SELECT
EXTENDED command is described in Table 3.1 as the value reported to the INIT by this
command, if parameter rounding processing is applied by the IDD, or in cases of a parameter or
bit with a specified value that is disregarded, different values than those specified by the INIT
will be reported. For details, see the descriptions of each page descriptor (in Section 3.1.5).
Also, "0" is reported in byte positions and bit positions which are reserved in each page
descriptor.
