C141-E167 4 - 13
00b= Perform disconnection according to the instructions of other parameters without
using DTDC.
01b= When a data transfer by the command is started, the target will never try
disconnection until transmission of all the data to be transferred by the command
is completed. The specified values in the "connect limit time" and "bus inactivity
limit" fields are ignored during the data transfer.
10b= Reserved.
11b= When a data transfer by the command is started, the target will never try
disconnection until execution of the command is completed. The specified
values in the "connect limit time" and "bus inactivity limit" fields are ignored
during the data tranfer.
h. Disconnect Immediate (DImm) (Not supported)
The IDD always control disconnection with itself algorithm. Therefore, The IDD disregards the
value specified in this parameter, and operates according to the "Default" value.
"0" : The IDD transfers data for a command during the same interconnect tenancy in which it
receives the command. Whether or not the target does so may depend upon the target's
internal algorithms, the rules of the applicable SCSI protocol, and settings of the other
parameters in this mode page.
"1" : The IDD does not transfer data for a command during the same interconnect tenancy in
which it receives the command.
i. Fair arbitration
This field indicates whether the target uses fair or unfair arbitration when requesting an

"000b" : Cannot use the arbitration fairness during a normal arbitration.
except above : Can use the arbitration fairness during a normal arbitration.
j. Enable modify data pointer (EMDP) (Not supported)
This bit indicates whether or not the initiator allows the data transfer to be re-ordered by the
target.
The IDD are not supported a MODIFY DATA POINTER message. Therefore, The IDD
disregards the value specified in this bit, and operates according to the "Default" value.
"0" : The IDD cannot transfer a MODIFY DATA POINTER message.
