Table 125 Standby Immediate Command (E0h/94h)

The Standby Immediate command causes the device to enter Standby mode immediately.

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 Standby Immediate command will not affect the auto power down timeout parameter.
