SiI3114 PCI to Serial ATA Controller
Data Sheet
Silicon Image, Inc.
SiI-DS-0103-D

2007 Silicon Image, Inc.
Feature Set
Mandatory for all Serial ATA components supporting the VS feature set.
Description
This command unlocks the host and device bridges to support vendor specific commands. Once this command is
executed, the bridge(s) shall remain unlocked until:
A VS Lock command that returns the VS state to the default locked state, or;
A hardware reset, or COMINIT or COMRESET.
Note that the VS Unlock Individual command, the VS Unlock Reserved command and Soft Reset have no effect
on the VS state.
If a VS Unlock Individual command is issued afterwards, the bridge(s) shall be unlocked for both individual vendor
specific/reserved commands and other vendor specific commands.
If a VS Unlock Reserved command is issued afterwards, the bridge(s) shall be unlocked for both vendor specific
and reserved commands.
If both VS Unlock Individual and VS Unlock Reserved are issued afterwards, the bridge(s) shall be unlocked for
individual vendor specific/reserved commands, as well as other vendor specific and reserved commands.
A Serial ATA host, native or bridge, supporting the VS Unlock Vendor Specific command shall use the non-data
(ext) protocol with this command. The Serial ATA host shall send this command to the Serial ATA device. The
following situations may happen:
Case 1: The Serial ATA device (native or bridge) responds with a completed status. Both sides are set up to
support this scheme.
Case 2: The Serial ATA device bridge supports this scheme. It may optionally pass this command to a
parallel ATA device:
If passed to a parallel ATA device, the parallel ATA device responds with an abort status, which may
be reported back to the Serial ATA host.
If not passed to a parallel ATA device, the device bridge shall still respond with a device-to-host
Register FIS to terminate BSY in the Serial ATA host.
However, both the Serial ATA host and the Serial ATA device bridge shall ignore the abort status and shall
consider the unlock event successful.
The Serial ATA device is a native device and responds with an abort. The Serial ATA host will ignore the abort
status and shall consider the unlock event successful.
In other words, regardless of the status reported (aborted or complete), the Serial ATA host and device that
support this scheme shall be unlocked to support vendor specific commands.
