(1)Header

a)Bytes 0 to 2

X '00' must be specified in this field.

b)Parameter length

The parameter list length in byte 4 and subsequent bytes which follows the header must be specified in this field. The parameter list length supported by the IDD is X '04' and the INIT must not specify a value other than X '04' in this field. If a value other than X '04' is specified, this command is terminated with a CHECK CONDITION status (ILLEGAL REQUEST [=5] / Invalid field in parameter list [=26-00]) and the operation mode are not changed.

(2)Parameter list

a)WDTR (wide data transfer request: Effective for 16-bit SCSI devices only.)

This specifies whether or not a wide mode data transfer request from the IDD is permitted. If this bit is set to 1, also set SDTR to 1. If only this bit is set but SDTR is not set, error code 5-26-00 is returned.

"1" (Permitted): After the power is switched on, after a RESET condition occurs or when the first command is received following reception of a BUS DEVICE RESET message, if a WIDE DATA TRANSFER REQUEST (WDTR) message is not sent by the INIT, the IDD sends the WDTR message and attempts to establish wide mode data transfer.

"0"* (Prohibited): If it is necessary to establish wide mode data transfer, the IDD does not send the WDTR message. However, if the INIT sends the WDTR message, the IDD responds normally.

*Set at shipping time

b)UNTATN (UNIT ATTENTION report mode)

This specifies the response method to commands received from the INIT when the IDD is holding a UNIT ATTENTION condition:

"1"* (Report): The IDD reports a CHECK CONDITION status (Standard SCSI specification) in response to commands other than INQUIRY and

REQUEST SENSE.

"0" (No Report): The IDD terminates all commands that are received normally. (A CHECK CONDITION status which causes a UNIT ATTENTION condition is not reported.)

*Set at shipping time
