Figure 95. Idle Immediate command (E1h/95h)

The Idle Immediate command causes the device to enter Performance Idle mode.

executed.
During Idle mode the device is spinning and ready to respond to the host commands immediately.
The Idle Immediate command will not affect the auto power down time-out parameter.
