13.9 Idle (E3h/97h)

Table 80: 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.
