Operation
The following summarizes how the vendor specific/reserved commands are supported. Detailed operations are
described in later sections.
The default state is locked. All vendor specific commands shall be aborted.
Unlock:
To unlock the Serial ATA host or device to support vendor specific commands: Issue a VS Unlock Vendor
Specific command. A Serial ATA host supporting the VS scheme will also send this command to the Serial
ATA device. If the downstream Serial ATA device is a bridge, the device bridge may optionally issue this
command to the attached parallel ATA device. Note that the unlock will take effect in the Serial ATA host
and the Serial ATA device even if an ABORT status is reported.
To unlock the Serial ATA host or device to support reserved commands: Issue a VS Unlock Reserved
command. A Serial ATA host supporting the VS scheme will also send this command to the Serial ATA
device. If the downstream Serial ATA device is a bridge, the device bridge may optionally issue this
command to the attached parallel ATA device. Note that the unlock will take effect in the Serial ATA host
and the Serial ATA device even if an ABORT status is reported.
To support individual vendor specific or reserved command: Issue a VS Unlock Individual command.
Combinations of the above can be supported by simply issuing the appropriate combinations of VS Unlock
Vendor Specific, VS Unlock Reserved and VS Unlock Individual commands.
Set protocol. There are two ways to set up protocol(s):
Issue a VS Set Command Protocol command to set up a protocol for a specific command. The information
is logged in a Command Protocol Table. This protocol shall remain valid until overwritten by a VS Set
Command Protocol command that overwrites the Command Protocol Table entry, the VS Lock command,
hardware reset, COMRESET, or COMINIT. A Serial ATA host supporting the VS scheme will also send this
command to the Serial ATA device. If the downstream Serial ATA device is a bridge, the device bridge may
optionally issue this command to the attached parallel ATA device. Note that the protocol shall be set in the
Serial ATA host and the Serial ATA device even if an ABORT status is reported. If more than one command
protocol has to be set up, a VS Set Command protocol shall be issued for each command.
Issue a VS Set General Protocol command to set the General Protocol Code for the next vendor specific
command. This protocol shall remain valid until the next VS Set General Protocol command, VS Lock
command, hardware reset, COMRESET, or COMINIT. A Serial ATA host supporting the VS scheme will also
send this command to the Serial ATA device. If the downstream Serial ATA device is a bridge, the device
bridge may optionally issue this command to the attached parallel ATA device. Note that the protocol shall
be set in the Serial ATA host and the Serial ATA device even if an ABORT status is reported. Commands
already set up via the VS Set Command Protocol shall follow the protocol set in the VS Set Command
Protocol command instead of the one set in this command.
Issue any commands:
Any vendor specific commands (if unlocked for vendor specific commands) or reserved commands (if
unlocked for reserved commands) that has an associated protocol set via the VS Set Command Protocol
command shall be executed using that protocol.
Any vendor specific commands (if unlocked for vendor specific commands) or reserved commands (if
unlocked for reserved commands) that does not have an associated protocol, i.e. not set up by the VS Set
Command Protocol command, shall be executed using the protocol loaded from the latest VS Set General
Protocol command.
Other supported commands shall follow the predefined protocols.
Other unsupported commands shall be aborted.
To change the protocol for vendor specific commands, simply reissue the VS Set General Protocol or the VS Set
Command Protocol command with the new protocol.
When done, issue the VS Lock command to return to the default VS state. A Serial ATA host supporting the VS
scheme will also send the VS Lock command to the Serial ATA device. If the downstream Serial ATA device is a
bridge, the device bridge may optionally issue this command to the attached parallel ATA device. Note that the
lock will take effect in the Serial ATA host and the Serial ATA device even if an ABORT status is reported.
