    Interface 8) If an uncorrectable error occurs during command queuing, the device sends to the host the Set Device Bits FIS with the settings of ERR bit = 1, ERRReg = ATAErrCode, I bit = 1, and SActive = 0 to report an error. 9) After reporting the error, the device accepts only the READ LOG EXT command with page 10h specified and the reset requests (SoftReset and COMRESET).

    Interface 5.5 Power-on and COMRESET Figure 5.20 shows the power-on sequence, and Figure 5.21 shows the COMRESET sequence. Immediately after power-on or COMRESET, the host sets 0x7Fh in the Status field of the Shadow Block Register and 0xFFh in other fields. After the power-on sequence shown below and after communication with the SATA interface is established, the host sets 0xFFh in the Status field of the Shadow Block Register.

    Operations 6.1 Reset and Diagnosis This section explains the device responses to power-on and an accepted reset. 6.1.1 Response to power-on Immediately after power is turned on, the host sets 0x7Fh in the Status field of the Shadow Block and 0xFFh in other fields. After communication with the SATA interface is established, the host sets 0xFFh in the Status field of the Shadow Block.

    Operations 6.1.2 Response to COMRESET The response to COMRESET is almost the same as the response when power is turned on and a power-on reset is then cancelled. The device establishes communication with the SATA interface (PHY Ready) and sends the RegDH FIS (STS = 50h) to notify the host that the device is ready.

  • Page 257: Software Settings Preservation

    6.1 Reset and Diagnosis 6.1.2.1 Software settings preservation When a device is enumerated, software will configure the device using SET FEATURES and other commands. These software settings are often preserved across software reset but not necessarily across hardware reset. In Parallel ATA, only commanded hardware resets can occur, thus legacy software only reprograms settings that are cleared for the particular type of reset it has issued.

  • Page 260: Power Save

    Operations 6.2 Power Save The host can change the power consumption state of the device by issuing a power command to the device. 6.2.1 Power save mode There are five types of power consumption state of the device including active mode where all circuits are active.
  • Page 261 6.2 Power Save • Upon receipt of a COMRESET • Upon receipt of Idle/Idle Intermediate (4) Standby mode In this mode, the spindle motor has stopped from the low power idle state. The device can receive commands through the interface. However if a command with disk access is issued, response time to the command under the standby mode takes longer than the active, active idle, or low power idle mode because the access to the disk medium cannot be made immediately.

    6.4 Read-ahead Cache 6.4 Read-ahead Cache Read-ahead Cache is the function for automatically reading data blocks upon completion of the read command in order to read data from disk media and save data block on a data buffer. If a subsequent command requests reading of the read-ahead data, data on the data buffer can be transferred without accessing the disk media.

    Operations 6.4.3 Using the read segment buffer Methods of using the read segment buffer are explained for following situations. 6.4.3.1 Miss-hit In this situations, the top block of read requested data is not stored at all in the data buffer. As a result, all of the read requested data is read from disk media. 1) HAP (host address pointer) and DAP (disk address pointer) are defined in the head of the segment allocated from Buffer.

  • Page 269: Sequential Hit

    6.4 Read-ahead Cache 6.4.3.2 Sequential hit When the read command that is targeted at a sequential address is received after execution of the read commands is completed, the read command transmits the Read requested data to the host system continuing read-ahead without newly allocating the buffer for read.
  • Page 270 Operations data that is a target of caching and remains before a full hit, the data is retained when execution of the command is completed. This is done so that a new read- ahead operation is not performed. If the full hit command is received during the read-ahead operation, a transfer of the read requested data starts while the read- ahead operation is in progress.

  • Page 271: Partial Hit

    6.4 Read-ahead Cache 6.4.3.4 Partial hit In this situation, a part of read requested data including the top sector is stored in the data buffer. A transfer of the read requested data starts from the address where the data that is hit is stored until the top sector of the read requested data. Remaining part of insufficient data is read then.

  • Page 272: Write Cache

    Operations 6.5 Write Cache Write Cache is the function for reducing the command processing time by separating command control to disk media from write control to disk media. When Write Cache is permitted, the write command can be keep receiving as long as the space available for data transfers remains free on the data buffer.
  • Page 273 6.5 Write Cache (3) Status report in the event of an error The status report concerning an error occurring during writing onto media is created when the next command is issued. Where the command reporting the error status is not executed, only the error status is reported. Only the status of an error that occurs during write processing is reported.
