13.40 Standby Immediate (E0h/94h)

Table 123: Standby Immediate (E0h/94h)

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

When this command is issued, the device confirms the completion of the cached write commands before it asserts

the INTRQ. Following the INTRQ the interface remains active and the device is spun down. 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.
