1. Maintain NOP input conditions for a minimum of 100us.
2. Issue PRECHARGE commands for all banks.
3. Issue two or more AUTO REFRESH commands.
In order to exit deep power-down mode, CKE must be asserted high. After exiting, the
following sequence is needed in order to enter a new command:
The values of the MODE REGISTER and EXTENDED MODE REGISTER will be retained
upon exit deep power down.
