This command is the only way to cause the device to enter Sleep Mode.
When this command is issued, the device confirms the completion of the cached write commands before it asserts
INTRQ. Then the device is spun down, and the interface becomes inactive. The only way to recover from Sleep
Mode is with a software reset or a COMRESET.
The use of hardware reset to recover from Sleep Mode may be incompatible with continued operation of the host
system.
If the device is already spun down, the spin down sequence is not executed.
