The device exits the Deep Power Down Mode asynchronously at the rising edge of the CKE signal.
After CKE goes high, the Device Deselect or No-operation command must be register at the immediately
following CLK rising edge, and CKE must remain high at least for tCKS delay immediately after exiting the
Deep Power Down Mode.
