Figure 134. Standby command (E2h/96h)
The Standby command causes the device to enter the Standby Mode immediately and to set the auto
power down time-out parameter (standby timer).
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 timer starts counting down when the device returns to Idle mode.
Output parameters to the device
Sector Count
The Time-out Parameter. If it is zero, the time-out interval (Standby Timer) is NOT
disabled but is automatically set to 109 minutes. If it is other than zero the
time-out interval is set for (Time-out Parameter × 5) seconds.
When the automatic power down sequence is enabled, the device will enter the
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.
