SiI3114 PCI to Serial ATA Controller
Data Sheet
Silicon Image, Inc.

SiI-DS-0103-D
A Serial ATA host, native or bridge, supporting the VS Set Command Protocol 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 protocol set.
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 protocol set.
In other words, regardless of the status reported (aborted or complete), the Serial ATA host and device that
support this scheme shall accept the protocol as valid.
State Transitions
Table 37 through Table 44 describe the state transitions of the SiI3114.
Table 37. Default State - VS_LOCKED
VS_LOCKED
Vendor specific/Reserved commands not supported. All vendor specific
and reserved commands shall result in an ABORT status.
General Protocol Code shall be 00h.
Command Protocol Table initialized with all Command Codes = 00h and
all Protocol Codes = 00h.

Table 38. VS_VS
VS_VS
On VS Set General Protocol command, set General Protocol Code.
Commands other than vendor specific or reserved commands shall be
executed according to the predefined protocol.
All vendor specific commands shall be executed according to the
General Protocol Code.
All reserved commands shall result in an ABORT status.
