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

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

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.
