Table  65 Idle Command (E3h/97h)   
When the power  save mode is Standby mode, the  Idle  command  causes the device to enter 
performance Idle mode immediat ely, 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  
Sector Count 
Timeout Parameter. If zero, the timeout interval(Standby Timer) is        disabled. If other than 
zero, the timeout interval is set for (Timeout Parameter x5) seconds. 
The device will enter Standby mode automatically if the timeout interval expires with no 
device access from the host. The timeout interval will be reinitial ized if there is a device 
access before the timeout interval expires.
