Default

Field Value Description

DTDC Data Transfer Disconnect Control. This field of three bits defines

further restrictions when a disconnect is permitted. These are as

follows:

Value Description

000b Data transfer disconnect control is not used. Disconnect is

controlled by other fields in this page.

001b A target shall not attempt to disconnect once the data

transfer of a command has started until all data of the

command has been transferred. The connect time limit

and bus inactivity limit are ignored during the transfer.

010b Reserved

011b A target shall not attempt to disconnect once the data

transfer of a command has started, until the command is

complete. The connect time limit and bus inactivity limit

are ignored once the transfer has started.

First Burst Size 0 This field indicates the maximum amount of data that a target may

transfer for a command during the same interconnect in which it

receieves the command.

NOTE: Fully supported and temporary fields are underlined. Unsupported fields are not

underlined. The PS bit is underlined, meaning it will be set on a MODE SENSE command,

since the page is savable.
