Feature Set
Optional for all Serial ATA components supporting the VS feature set.
Description
If the VS state is unlocked for individual vendor specific/reserved commands, this command will set the protocol
for the specific commands. Up to 16 individual vendor specific/reserved commands are supported via a
Command Protocol Table. The 16 entries are organized as shown in Table 35.

When a vendor specific or reserved command is issued, its Command and Features registers will be compared
against all of the above entries. If the following conditions are all met, the protocol for that entry will be used:
Command = Command Code, and;
(Features ⊕ Features Code) & Features Mask = 00h.
Note that:
Only reserved and vendor specific commands shall be mapped to protocol as above.
If a vendor specific or reserved command is mapped to more than one entry, the result is indeterminate.
Upon a lock event, all Command Codes shall be initialized to NOP (00h) and all Protocol Codes shall be
initialized to Abort (00h). The following conditions are considered lock events:
A VS Lock command to return the VS state to the default locked state, or;
A hardware reset, or COMINIT or COMRESET.
The registers shown in Table 36 are used when issuing the command (but have no meaning for outputs)
