Spread Spectrum Clocking (SSC)
In SATA software, turns SSC on or off. Can only be set
outside Generation block.
In SAS software, when you turn on SSC, Trainer PHY
can turn on SSC on the PHY. In the SAS protocol,
during speed negotiation, when both sides of a link
agree to turn on their SSC, SSC will turn on, with the
SSC Type and SSC Amplitude parameters.
Specifies SSC type as midspread.
Specifies SSC Amplitude. Possible values are:
SSC_AMP_500
SSC_AMP_1000
SSC_AMP_1500
SSC_AMP_2000
SSC_AMP_2500
SSC_AMP_3000
0
When set, the change of speed within Generation
block is allowed with following syntax: set Speed =
LINK_SPEED_1_5G / LINK_SPEED_3G /
LINK_SPEED_6G
0
This very poorly named register bit forces the Trainer
to output data. It is a little like the output_on script
command except that its effect cannot be undone for
the duration of the script. If this is turned on, none of
the out‐of‐band commands will work, as the output
enable is forced on.

When set, in "Connect command" SNW1 will be tried
in Speed Negotiation phase
Can only be set outside Generation block.

When set, in "Connect command" SNW2 will be tried
