Figure 94. 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 sets the auto power down time-out Parameter (standby timer). At the set of the
auto power down time-out parameter (standby timer) the point timer starts counting down. When the
power save mode is already any idle mode, the device remains in 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 is ready to respond to host commands immediately.
Input parameters to the device
Sector Count This indicates the Time-out Parameter. If it is zero, the time-out interval (Standby
Timer) is NOT disabled and the time-out interval is set automatically for
109 minutes. If it is other than zero, the time-out interval is set for (Time-out
Parameter × 5) seconds.
The device will enter Standby mode automatically if the time-out interval expires
with no device access from the host. The time-out interval will be reinitialized if
there is a device access before the time-out interval expires.
