Table 64 Idle Command (E3h/97h)

When the power save mode is Standby mode, the Idle command causes the device to enter

performance Idle mode immediately, and set auto power down timeout parameter(standby timer).
And then the timer starts counting down. When the device’s power save mode is already any idle

mode, the device keep that mode.
When  the  Idle  mode  is  entered,  the  device  is  spun  up  to  operating  speed.  If  the  device  is  already
spinning, the spin up sequence is not executed.
During Idle mode the device is spinning and ready to respond to host commands immediately.

Output Parameters To The Device

device access from the host. The timeout interval will be reinitialized if there is a device
access before the timeout interval expires.
