Spread Spectrum Clocking (SSC) - ATA command?

I've looked at the ATA-8 spec but I can't find any mention of Spread Spectrum Clocking (SSC).

Could someone please tell me which ATA commands are used to enable/disable SSC?

I presume it would be a subcommand of the Set Features command.

Is the status of the SSC feature set reported via the Identify Device or DCO data blocks?
