Test 9.5.3 - SSP RESPONSE IU – DATAPRES RESERVED

Purpose: To determine that the DUT, an SSP Initiator, properly handles a response frame received with a reserved
value in the DATA PRES field.

References:

7.16.7.7, 9.2.2.5.1 SAS Standard

Resource Requirements: SAS Protocol Analyzer and Generator.

Revision History: September 27, 2004

Test Setup: The DUT and the Testing Station are physically connected.

Test Procedure (SSP Initiator):

• The Testing Station should start and complete a Phy Reset sequence followed by an Identify sequence

with the DUT. Since the DUT is a target the Testing Station should transmit an Identify Address frame
indicating that it is a target.

• Allow the DUT to open a connection to the Testing Station and transmit an INQUIRY command.

Close the connection.

• The Testing Station should transmit DATA and RESPONSE to the command from the DUT. The

Testing Station should set the DATAPRES field in the Response frame to 11b, a reserved value.

Observable Results: Verify that if the DUT discards the response frame that is received with a reserved value in the
DATAPRES field. The DUT should not ACK or NAK this frame.
