Figure 118. Sleep Command (E6h/99h)
This command causes the device to enter the Sleep Mode.
The device is spun down and the interface becomes inactive. If the device is already spun down, the spin
down sequence is not executed.
The only way to recover from the Sleep Mode is with a software reset or a hardware reset.
