SiI3114 PCI to Serial ATA Controller

Feature Set
Mandatory for all Serial ATA components supporting the VS feature set.
Description
If the VS state is unlocked for vendor specific or for reserved, this command will set the General Protocol Code
for the next vendor specific/reserved command(s), except for those individually set via the VS Set Command
Protocol commands. The protocol shall be, or return to, Abort (Protocol Code = 00h) upon a lock event, i.e.:
A VS Lock command to return the VS state to the default locked state, or;
A hardware reset, or COMINIT or COMRESET.
The General Protocol shall be passed to the Serial ATA host and device via the Expanded Sector Count register.
The protocols and codes are described in Table 45 through Table 48.
A Serial ATA host, native or bridge, supporting the VS Set General 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.
