Table 109 Sleep Command (E6h/99h)
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.
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.
If the device is already spun down, the spin down sequence is not executed.
