12.44 Standby Immediate (E0h/94h)
Table 129: Standby Immediate (E0h/94h)
The Standby Immediate command causes the device to enter the Standby mode immediately.
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, however there will be a delay while waiting for
the spindle to reach operating speed.
The Standby Immediate command will not affect the auto power down time-out parameter.
