After the command execution, self refresh operation continues while CKE
remains low. When CKE goes to high, the M12L2561616A exits the self refresh
mode.
During self refresh mode, refresh interval and refresh operation are performed
internally, so there is no need for external control.
WE
Before executing self refresh, all banks must be precharged.
