2. CAh 35h extended This command executes in a similar manner to Write Sector s except the drive issues only one interrupt per command to indicate that data transfer has terminated and status is available Any error encountered during Write DMA execution results in the termination of data transfer The drive issues an interrupt to indicate that data transfer has terminated and the status is available in the Error register The error posting is the same as that for the Write Sector s command 8 2 39 Write FPDMA Queued 61h This command is implemented according to the Serial ATA II Extension to Serial ATA 1 0a Revision 1 2 specification The purpose of this command is for the host to issue a Native Command Queue NCQ write commands This command allows device to reorder the command issued in a sequence of the queue The command is returned based on the device s determine of the location sequence The Spinpoint M8 drive implemented a queue depth of 32 This will allow host to issue up to 32 NCQ commands combined read and write commands If the drive enters NCQ mode and a non queue command is received the drive will respond with error to inform host a queue command been overlapped with non queue If a queue tag is not finished and another same tag command is received the drive will response with error to inform host a duplicated tag is received Error information is reported according to the SATA II specification A read Log Extended

Dword or 4 an encoded character that translates to any control character valid or invalid in bytes 1 3 of a Dword COMMA CHARACTER A comma character is a control character that when encoded contains the comma sequence In Serial ATA the only comma character used is K28 5 and only the ALIGN primitive contains the comma character The comma sequence is the first seven bits of the encoded character COMMA SEQUENCE The comma sequence is a seven bit sequence of 0011111 or 1100000 in an encoded stream The comma sequence is unique in that it appears only in a single encoded character and furthermore cannot appear in any subset of bits in adjacent encoded characters This unique property allows the comma sequence to be used for determining alignment of the received data stream COMRESET COMINIT Host Signal from the out of band detector that indicates the COMINIT out of band signal is being detected CONTROL CHARACTER A control character is a combination of a byte value with the control variable equal to K CONTROL VARIABLE The control variable Z is a flag that determines the code set to be used to interpret a data byte The control variable has the value D for data characters or K for control characters CRC In Serial ATA a 32 bit CRC is calculated over the contents of a FIS The Serial ATA CRC is the Dword in a frame that immediately precedes the EOF primitive Spinpoint M8 DVR Disti Product Manual REV 2 0 35 DATA CHARA

A SATA also allows a data transfer speed of 150 MB s 300 MB s and 600 MB s Even though SATA will not directly interface with Parallel or traditional ATA PATA hardware it is compliant with ATA protocol and therefore software compatible The cable geometry with smaller footprint connector reduces board space requirements and improves air flow and heat exchange inside computer systems SATA uses point to point connection topology and each channel works independently There is no sharing of interface master slave drive configuration and no master slave jumper settings This is different from Parallel ATA PATA architecture where 2 drives per port are supported by a shared bus and drives are designated as master or slave drive based on jumper pin or cable selection Unlike parallel ATA SATA drives are hot plug and hot swappable 1 4 Reference For additional information about the AT interface refer to Ll O O O O O O ATA 2 AT Attachment 2 Revision 3 January 1995 ATA 3 Attachment 3 Interface Revision 7b 27 January 1997 ATA 4 AT Attachment with Packet Interface Extension Revision 18 19 August 1998 ATA 5 AT Attachment with Packet Interface Extension Revision 3 29 February 2000 ATA 6 AT Attachment with Packet Interface Extension Revision 2a 26 September 2001 ATA 7 AT Attachment with Packet Interface Extension Revision 1 28 August 2002 ATA 8 AT Attachment with Packet Interface Extension Revision 0 16 Septe

26. CTER A data character is a combination of a byte value with the control variable equal to D DWORD A Dword is thirty two 32 bits of data A Dword may be represented as 32 bits as two adjacent words or as four adjacent bytes When shown as bits the least significant bit is bit O and most significant bit is bit 31 The most significant bit is shown on the left When shown as words the least significant word lower is word 0 and the most significant upper word is word 1 When shown as bytes the least significant byte is byte 0 and the most significant byte is byte 3 DWORD SYNCHRINIZATION The state in which a receiver has recognized the comma sequence and is producing an aligned data stream of Dwords four contiguous bytes from the zero reference of the comma character ENCODED CHARACTER An encoded character is the output of the 8b 10b encoder the result of encoding a character An encoded character consists of 10 bits where bit O is the most significant bit and bit 9 is the least significant The bits in an encoded character are symbolically referred to as abcdeifghj where 66 a corresponds to bit 0 and j corresponds to bit 9 ELASTICITY BUFFER The elasticity buffer is a portion of the receiver where character slipping and or character alignment is performed FIRST PARTY DMA ACCESS First party DMA access is a method by which a device accesses host memory FIRST PARTY DMA MODE FPDMA A device which is operating in
