3.1 Control/Sense Commands

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."

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.

Notes:

1.The MODE SELECT parameter is ordinarily different in its configuration depending on the input/output device and the type of controller. It is also possible that current definitions may be expanded in accordance with the expansion of the functions of the IDD in the future. In order to assure independence of software from the individual specifications of input/output devices, before the INIT issues this command, it should follow the procedure of using the MODE SENSE and MODE SENSE EXTENDED command to determine the types of parameters the TARG is actually equipped with and the attributes of those parameters, such as whether or not they can be changed.
