Table  125 Standby Command (E2h/96h)   
The Standby command causes the device to enter the Standby Mode immediately, and set auto power 
down timeout parameter(standby timer).  
When this command is issued, the device confirms the completion of the cached write commands. 
Then the device is spun down, but the interface remains active.  
If the device is already spun down, the spin down sequence is not executed.  
During the Standby mode the device will respond to commands, but there is a delay while waiting 
for the spindle to reach operating speed.  
The timer starts counting down when the device returns to Idle mode.  
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.  
When the automatic power down sequence is enabled, 
The device will enter Standby mode automatically if the timeout interval expires with 
no device access from the host. The timeout interval will be reinitialized if there is a 
device access before the timeout interval expires.
