  • Page 70: Set Multiple Mode - C6H

    ATA C OMMAND LOCK AND Set Multiple Mode — C6h The Set Multiple Mode command allows the host to access the drive via Read Multiple and Write Multiple ATA commands. Additionally, the command sets the block count (i.e., the number of sectors within the block) for the Read/Write Multiple command.

  • Page 71: Set Sleep Mode - 99H, E6H

    ATA C OMMAND LOCK AND Set Sleep Mode — 99h, E6h The Set Sleep Mode command allows the host to set the device in sleep mode. When the onboard controller transitions to sleep mode, it clears the BSY bit and issues an interrupt. The device interface then becomes inactive. Sleep mode can be exited by issuing either a hardware or software reset.

  • Page 72: Standby - 96H, E2H

    ATA C OMMAND LOCK AND Standby — 96h, E2h When the Standby command is issued by the host, it transitions the device into standby mode.

  • Page 76: Write Multiple - C5H

    ATA C OMMAND LOCK AND Write Multiple — C5h The Write Multiple command operates in the same manner as the Write Sector command. When issued, the device sets the BSY bit within 400ns and generates an interrupt at the completion of a transferred block of sectors. The DRQ bit is set at the beginning of a block transfer.

  • Page 77: Write Sector(S) - 30H, 31H

    ATA C OMMAND LOCK AND Write Sector(s) — 30h, 31h The Write Sector(s) command writes from 1 to 256 sectors as specified in the Sector Count register. A sector count of 0 requests 256 sectors. When issued, the device sets the BSY bit within 400ns and generates an interrupt at the completion of a transferred block of sectors.

  • Page 78: Write Long Sector(S) - 32H, 33H

    ATA C OMMAND LOCK AND Write Long Sector(s) — 32h, 33h The Write Long Sector(s) command operates in the same manner as the Write Sector command — when issued, the device sets the BSY bit within 400ns and generates an interrupt at the completion of a transferred block of sectors. The DRQ bit is set at the beginning of a block transfer.

  • Page 79: Erase Sector(S) - C0H

    ATA C OMMAND LOCK AND Erase Sector(s) — C0h The Erase Sector(s) command is issued prior to the issuance of a Write Sector(s) or Write Multiple w/o Erase command.

  • Page 82: Wear-Level - F5H

    ATA C OMMAND LOCK AND Wear-Level — F5h The Wear-Level command is supported as an NOP command for the purposes of backward compatibility with the ANSI AT attachment standard. This command sets the Sector Count register to 0x00h. Register Feature Sector Count Sector Number Cylinder Low...

  • Page 83: Write Multiple W/O Erase - Cdh

    ATA C OMMAND LOCK AND Write Multiple w/o Erase — CDh The Write Multiple w/o Erase command functions identically to the Write Multiple command, with the exception that the implied pre-erase (i.e., Erase Sector(s) command) is not issued prior to writing the sectors. Table 61: Write Multiple w/o Erase —...

  • Page 84: Write Sector(S) W/O Erase - 38H

    ATA C OMMAND LOCK AND Write Sector(s) w/o Erase — 38h The Write Sector(s) w/o Erase command functions similar to the Write Sector command, with the exception that the implied pre-erase (i.e., Erase Sector(s) command) is not issued prior to writing the sectors. Table 62: Write Sector(s) w/o Erase —...
