Description
This command unlocks the SiI3512 to support vendor-specific commands. Once this command is executed, the SiI3512
will 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 SiI3512 controller will be unlocked for both
individual vendor-specific/reserved commands and other vendor-specific commands.
If a VS Unlock Reserved command is issued afterwards, the SiI3512 controller will be unlocked for both vendor-
specific and reserved commands.
If both VS Unlock Individual and VS Unlock Reserved are issued afterwards, the SiI3512 controller will be
unlocked for individual vendor-specific/reserved commands, as well as other vendor-specific and reserved
commands.
The SiI3512 will use the non-data (ext) protocol with this command. The SiI3512 will 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.
