Vendor-Specific Command Support
The SiI3512 controller supports most vendor-specific commands that utilize existing protocols.
Silicon Image's Vendor-Specific Commands
Silicon Image defines several vendor-specific commands (all of which use Expanded Features in 48-bit LBA addressing)
to support vendor-specific and reserved commands:
VS Unlock Vendor Specific: Unlock the host or device to support vendor-specific commands.
VS Unlock Reserved: Unlock the host or device to support reserved commands.
VS Unlock Individual: Unlock the host or device to support individual vendor-specific and reserved commands.
VS Lock: Lock the host or device to abort all vendor-specific and reserved commands.
VS Set General Protocol: Determine the General Protocol Code to be used for all subsequent vendor-specific
commands (if unlocked via a VS Unlock Vendor Specific command) and reserved commands (if unlocked via a
VS Unlock Reserved command).
VS Set Command Protocol: Select protocols for individual vendor-specific and reserved commands (if unlocked
via a VS Unlock Individual command). A Command Protocol Table will be maintained. Commands set up via this
will follow the protocol set in this command instead of the original command protocol. Hence, commands can be
―overloaded‖ using this method.
Potential Conflicts with Other Vendor-Specific Commands
The commands chosen use Subcommand (Features) code 0xF1 under the SMART command (0xB0). While this code is
not expected to be used by device manufacturers, there is always the possibility that it is used. If such conflict happens,
the device manufacturers must reassign a new code to the conflicting command in order to use this scheme.
Other Expanded Features Codes
The commands above use some of the l Expanded Features Codes. All Expanded Features Codes under Command Code
0xB0 and Subcommand (Features) Code 0xF1 are reserved as Silicon Image vendor-specific commands.
Vendor-Specific, Reserved, Retired and Obsolesced Commands
These types of commands are treated differently:
Vendor-specific commands: Expect for those commands whose protocols are individually set (via the VS Unlock
Individual and VS Set Command Protocol commands), the host or device must be unlocked via the VS Unlock
