4.1.5.2.1 Configure Stream (51h) The Configure Stream command specifies the default CCTL (Command Completion Time Limit) for streaming commands, and informs the drive of the Allocation Unit size and alignment. Protocol: non-data Register Features 7 6 Current Ignored R/W 5 4 3 Reserved 2 1 0 Ignored Sector Count Previous Current Default CCTL (7:0) AU Size In Sectors (7:0) Previous LBA Low, Mid, High Current AU Size In Sectors (15:8) Reserved Previous Reserved Device obs Ignored obs DEV Reserved Command 51h Note: The value indicated as Current is the value most recently written to the register. The value indicated as Previous is the value that was in the register before the most recent write to the register. FEATURES REGISTER FIELD DESCRIPTIONS R/W 0 Read stream 1 Write stream Default CCTL (Default Command Completion Time Limit) This value is calculated as follows (with the unit of measure being microseconds): Default CCTL = ((content of the Features register) * (IDENTIFY DEVICE words (99:98)) This time shall be used by the drive when an individual streaming command with a CCTL of 0 is issued. The time is measured from the write of the command register to the final INTRQ for command completion. SECTOR COUNT REGISTER FIELD DESCRIPTIONS Current The size of an Allocation Unit in sectors (bits 7:0). Previous The size of an Allocation Unit in sectors (bits 15:8) DEVICE REGISTER FIELD DESCRIPTIONS Dev The selected device. SV35 Series Product Manual, Rev. B 41
