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 HDD are transferred to the
INIT in the ascending order of the page code. Also, when X '00' is specified in the
"Page code field," the "Page descriptor" is not transferred. If page codes other
than the above mentioned ones ("Page descriptors" which are not supported by the
HDD) 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 4.16.
Even in cases where the value specified in the MODE SELECT or
MODE SELECT EXTENDED command is described in Table 4.16
as the value reported to the INIT by this command, if parameter
rounding processing is applied by the HDD, 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 Chapter 5). Also,
"0" is reported in byte positions and bit positions which are reserved
in each page descriptor.
