DTDC Data Transfer Disconnect Control. This field of three bits defines further restrictions
when a disconnect is permitted. These are as follows:

ed fields are not underlined. The PS bit is underlined, meaning
it will be set on a MODE SENSE command, since the page is
savable.
Enable MODIFY DATA POINTER.
Indicates whether or not the target should use fair or unfair (e.g., prior-
ity) arbitration when beginning the interconnect tenancy.
Description
Disables the fairness algorithm. A fixed priority scheme based on the
SCSI ID assigned is used.
Any non-zero value enables the fairness algorithm (SCSI SPI-2 ANSI
standard, Appendix B).
Disconnect Immediate. When set to a 1, to reduce on-bus time, the
drive is forced to disconnect from the SCSI Bus after a SCSI Command
is received. Disconnect Immediate works only when a typical, error-free
command is received. Disconnect Immediate does not apply in excep-
tion conditions (for example, SDTR received, error, etc.).
Description
Data transfer disconnect control is not used. Disconnect is controlled
by other fields in this page.
A target will not attempt to disconnect once the data transfer of a com-
mand has started until all data of the command has been transferred.
The connect time limit and bus inactivity limit are ignored during the
transfer.
Reserved
A target will not attempt to disconnect once the data transfer of a com-
mand has started, until the command is complete. The connect time
limit and bus inactivity limit are ignored once the transfer has started.
This field indicates the maximum amount of data that a target may
transfer for a command during the same interconnect in which it re-
ceives the command.
