(30) SET FEATURES (X’EF’)
The host system issues the SET FEATURES command to set parameters in the
Features field for the purpose of changing the device features to be executed.
Upon receipt of this command, the device sets the parameters in the Features field,
then reports the status to the host system.
If the value in the Features field is not supported or it is invalid, the device posts an
ABORTED COMMAND error.
