Note: The device exit the Self Refresh mode asynchronously at the rising edge of the CKE signal.
After CKE goes high, the Device Deselect or No-operation command must be registered at the immediately following
CLK rising edge, and CKE must remain high at least for tCKS delay immediately after exit the Self Refresh Mode.
A bust of 8K auto refeesh cycle within 7.8us before entering and exiting is necessary if the system does not use the
auto refresh function.
