o Check Word 86 bit 3 (set to one)
o Issue SET FEATURES to alter setting for APM enable/disable
o If Word 86 bit 3 is set to one,
 Check value of Word 91 bits 7:0
o Issue COMRESET and complete OOB sequence
o Check Word 83 bit 3,
o If Word 86 bit 3 is set to one,
 Check value of Word 91 bits 7:0
• Verify that IDENTIFY DEVICE Word 86 bit 3 contains the same value following COMRESET
Pass/Fail Criteria
o If Word 86 bit 3 was set to one, verify that IDENTIFY DEVICE 91 bits 7:0 contains the same value
following COMRESET
2.4.8. SSP-08 : Set Features – Read Look-Ahead
2.4.8.1. Device Expected Behavior
NOTE - To test the following requirement, a device must claim support for look-ahead (Word 82 bit 6 set to one in
IDENTIFY DEVICE or IDENTIFY PACKET DEVICE data).
Upon receipt of a COMRESET, a device shall maintain the value of look-ahead enable/disable. Specifically, if support
for look-ahead is enabled (Word 85 bit 6 set to one in IDENTIFY DEVICE or IDENTIFY PACKET DEVICE data) upon
receipt of a COMRESET then the feature shall be enabled after the COMRESET. If support for look-ahead is
disabled (Word 85 bit 6 cleared to zero in IDENTIFY DEVICE or IDENTIFY PACKET DEVICE data) upon receipt of a
COMRESET then the feature shall be disabled after the COMRESET.
• Check Word 78 bit 6 in IDENTIFY DEVICE or IDENTIFY PACKET DEVICE (set to one)
Measurement Requirements
• Check Word 82 bit 6 (set to one)
• If the above is false, then the test is not applicable
• Otherwise, run the following test
o Check value of Word 85 bit 6
o Issue SET FEATURES to alter setting for read look-ahead enable/disable
o Issue COMRESET and complete OOB sequence
o Check value of Word 85 bit 6
• Verify that IDENTIFY DEVICE or IDENTIFY PACKET DEVICE Word 85 bit 6 contains the same value
following COMRESET
Pass/Fail Criteria
2.4.9. SSP-09 : Set Features – Release Interrupt
2.4.9.1. Device Expected Behavior
NOTE - To test the following requirement, a device must claim support for release interrupt (Word 82 bit 7 set to one
in IDENTIFY DEVICE or IDENTIFY PACKET DEVICE data).
Upon receipt of a COMRESET, a device shall maintain the value of release interrupt enable/disable. Specifically, if
support for release interrupt is enabled (Word 85 bit 7 set to one in IDENTIFY DEVICE or IDENTIFY PACKET
DEVICE data) upon receipt of a COMRESET then the feature shall be enabled after the COMRESET. If support for
release interrupt is disabled (Word 85 bit 7 cleared to zero in IDENTIFY DEVICE or IDENTIFY PACKET DEVICE
data) upon receipt of a COMRESET then the feature shall be disabled after the COMRESET.
• Check Word 78 bit 6 in IDENTIFY DEVICE or IDENTIFY PACKET DEVICE (set to one)
Measurement Requirements
• Check Word 82 bit 7 (set to one)
