Figure 83. Idle Command (E3h/97h)
The Idle command causes the device to enter Idle mode immediatly, and set auto power down timeout
parameter(standby timer). And then the timer starts counting down.
When the Idle mode is entered, the device is spun up to operating speed. If the device is already spin-
ning, 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 NOT dis-
abled, but the timeout interval is set for 109 minutes automatically. If it is 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 reinitialized if
there is a device access before the timeout interval expires.
