c. Page descriptor
The "Page descriptor" is configured from a 2-byte page header followed by a parameter field and
each parameter function attribute is classified in a unit called a "Page." The individual "Page
descriptors" in the MODE SELECT and MODE SELECT EXTENDED commands may be specified
independently by the INIT and multiple "Page descriptors" may be specified continuously in the
desired sequence.
•
Page code
This field specifies a code (Page No.) that indicates the type of "Page descriptor."
•
SPF (sub page format)
A setting of "0" in this bit indicates that Page_0 Format (Short Page Format) is used. A setting
of "1" in this bit indicates that Sub_Page Format (Long Page Format) is used.
If "1" is specified for a page (excluding page 19) that does not support the Sub_Page Format, the
MODE SELECT command terminates with the "CHECK CONDITION" status (ILLEGAL
REQUEST [=5] / Invalid Field in Parameter List [=26/00]), and all parameters specified by this
command are invalidated.
•
Page length
This field indicates the length of the parameter field (number of bytes) after byte 2, excluding
the page header, of the "Page descriptor" and is a fixed value for each page code. The INIT
must specify the same value as the page length reported by the IDD in the MODE SENSE or
MODE SENSE EXTENDED command, except in cases it is described in each of the page
descriptor descriptions in this item.
d. MODE SELECT parameters of the IDD
The parameter list configuration and its length that can be transferred to the IDD by the INIT in the
MODE SENSE or MODE SENSE EXTENDED command are as shown below.
descriptor" that is not supported by the IDD is specified, the command is terminated with a CHECK
CONDITION status (ILLEGAL REQUEST [=5] / Invalid field in parameter list [=26-00]), and all
the MODE SELECT parameters transferred in the command are disabled.
