ABSTRACT

This standard specifies the AT Attachment command set used to communicate between host systems and

storage devices. This provides a common command set for systems manufacturers, system integrators,

software suppliers, and suppliers of storage devices. The AT Attachment command set includes the PACKET

feature set implemented by devices commonly known as ATAPI devices. This standard maintains a high degree

of compatibility with the AT Attachment Interface with Packet Interface - 7 (ATA/ATAPI-7) volume 1 (see ANSI

INCITS 397-2004).

American

National

Standard

Approval of an American National Standard requires verification by ANSI that the

requirements for due process, consensus, and other criteria for approval have been met by

the standards developer. Consensus is established when, in the judgment of the ANSI

Board of Standards Review, substantial agreement has been reached by directly and

materially affected interests. Substantial agreement means much more than a simple

majority, but not necessarily unanimity. Consensus requires that all views and objections be

considered, and that effort be made towards their resolution.

The use of American National Standards is completely voluntary; their existence does not in

any respect preclude anyone, whether he has approved the standards or not, from

manufacturing, marketing, purchasing, or using products, processes, or procedures not

conforming to the standards.

The American National Standards Institute does not develop standards and will in no

circumstances give interpretation on any American National Standard. Moreover, no person

shall have the right or authority to issue an interpretation of an American National Standard

in the name of the American National Standards Institute. Requests for interpretations

should be addressed to the secretariat or sponsor whose name appears on the title page of

this standard.

CAUTION NOTICE: This American National Standard may be revised or withdrawn at any

time. The procedures of the American National Standards Institute require that action be

taken periodically to reaffirm, revise, or withdraw this standard. Purchasers of American

National Standards may receive current information on all standards by calling or writing the

American National Standards Institute.

If no patents have been disclosed place the statement in 5.5.2 shall be used.

If any patents have been disclosed place the statement in 5.5.3 shall be used.

Revision History (part 1 of 21)

Rev

Date

Description

August 17, 2004

1) Initial revision created from ATA/ATAPI-7 Volume 1 (1532D Rev 4b).

2) Removed 3 volume structure and changed abstract to reflect a

command set document

3) Removed sections on signal, bit, and timing conventions

4) Removed clause 5, I/O register descriptions

5) Kept informative annex’s A-C

September 7, 2004

1) Restructured all commands to conform to format agreed to in e04139r4.

2) Added a section defining status bits

3) Added a section defining error bits

4) Added a section describing protocols

5) Added a section describing interrupt reason

6) Incorporated single log table e04143r0 table. Did not add wording to

status that host VS pages are common between SMART and GPL.

7) Removed prohibited statements from command definitions. These

reside in the feature set definitions.

October 6, 2004

1) Replaced duplicate Normal Outputs tables with a see clause to the first

usage.

2) Replaced many Error Outputs with a see clause.

February 17, 2005

1) Stripped unused informative references

2) Changed the definition of ordered and unordered lists to make the

numeric form ordered.

3) Changed all the lists to conform to the changes in #2

4) Reserved 5Ch-5Fh for TCG. This was done by added command

headers and a reserved statement in the command section. Also

marked the commands with T in the command matrix table.

5) Moved Normal and Error Outputs to their own section. Commands now

have a hotlink to the tables.

6) Moved IDENTIFY (PACKET) DATA to its own section (Input Data)

7) Changed more of the titles to be consistent with the front cover.

8) Deleted unused definitions

9) Changed the General feature set to only apply to non-packet devices

10) Changed the packet feature set to include all the commands in the

packet feature set.

11) The command prohibitions are now found in the feature set description

and not with each command.

12) Integrated e04127r0 – This makes SATA signatures reserved with no

description.
