Specifications

SATA-IO Confidential 25
NOTE - To test the following requirement, a device must claim support for Host Protected Area (Word 82 bit 10 set to
one in IDENTIFY DEVICE data).
Upon receipt of a COMRESET, a device shall maintain the max address established by the SET MAX ADDRESS or
SET MAX ADDRESS EXT command. Specifically, the value contained within Words 61:60 in IDENTIFY DEVICE data
shall be maintained after a COMRESET.
If 48-bit support is enabled by the device (Word 83 bit 10 set to one in IDENTIFY DEVICE data), then the values
contained within Words 103:100 in IDENTIFY DEVICE data shall also be maintained after a COMRESET.
• Check Word 78 bit 6 in IDENTIFY DEVICE (set to one)
Measurement Requirements
• Check Word 82 bit 10 in IDENTIFY DEVICE (set to one)
• If the above is false, then the test is not applicable
• Otherwise, run the following test
o Issue READ NATIVE MAX ADDRESS (or READ NATIVE MAX ADDRESS EXT) to get max user
accessible address.
o Issue SET MAX ADDRESS (or SET MAX ADDRESS EXT) with new valid max accessible address
o Check value of Word 83 bit 10
o Check value of Words 61:60
o If Word 83 bit 10 is set to one, also check value of Words 103:100
o Verify correct address is set due to SET MAX ADDRESS (EXT) command
o Issue COMRESET and complete OOB sequence
o Check value of Words 61:60
o If Word 83 bit 10 is set to one, also check value of Words 103:100
• Verify that IDENTIFY DEVICE Words 61:60 contain the same values following COMRESET, additionally if
Word 83 bit 10 is set to one verify that Words 103:100 contain the same values following COMRESET
Pass/Fail Criteria
2.4.5. SSP-05 : Set Features – Write Cache Enable/Disable
2.4.5.1. Device Expected Behavior
NOTE - To test the following requirement, a device must claim support for Write Cache (Word 82 bit 5 set to one in
IDENTIFY DEVICE or IDENTIFY PACKET DEVICE data).
Upon receipt of a COMRESET, a device shall maintain the value of write cache enable/disable. Specifically, if write
cache is enabled (Word 85 bit 5 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 write cache is disabled (Word 85 bit 5
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 value of Word 82 bit 5 (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 5
o Issue SET FEATURES to alter setting for Write Cache enable/disable
o Issue COMRESET and complete OOB sequence
o Check value of Word 85 bit 5
• Verify that IDENTIFY DEVICE or IDENTIFY PACKET DEVICE Word 85 bit 5 contains the same value
following COMRESET
