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.
x Page code
This field specifies a code (Page No.) that indicates the type of "Page descriptor."
x 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. If a
"Page 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.
