SET FEATURES (EFh)
The SET FEATURES (EFh) command writes the subfeature parameters (P1–P4) to the
specified feature address to enable or disable target-specific features. This command is
accepted by the target only when all die (LUNs) on the target are idle.
Writing EFh to the command register puts the target in the set features mode. The target
stays in this mode until another command is issued.
The EFh command is followed by a valid feature address. The host waits for tADL before
the subfeature parameters are input. When the asynchronous interface is active, one
subfeature parameter is latched per rising edge of WE#.
After all four subfeature parameters are input, the target goes busy for tFEAT. The READ
STATUS (70h) command can be used to monitor for command completion.
Feature address 01h (timing mode) operation is unique. If SET FEATURES is used to
modify the interface type, the target will be busy for tITC.
