Table 126 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.
