(14) SET FEATURES (X’EF’)
The host system issues the SET FEATURES command to set parameters in the
Features register for the purpose of changing the device features to be executed.
Upon receipt of this command, the device sets the BSY bit of the Status register
and saves the parameters in the Features register. Then, the device clears the
BSY bit, and generates an interrupt.
If the value in the Features register is not supported or it is invalid, the device
posts an ABORTED COMMAND error.
Table 5.5 lists the available values and operational modes that may be set in the
Features register.
