M52S64322A cannot accept any other command.
Self refresh entry command
When CKE goes to high, the M52S64322A exits the self refresh mode.
internally, so there is no need for external control.
Before executing self refresh, all banks must be precharged.
Burst stop command
This command terminates the current burst operation.
Burst stop is valid at every burst length.

This command is a request to begin the CBR refresh operation. The refresh address
Before executing CBR refresh, all banks must be precharged.
After this cycle, all banks will be in the idle (precharged) state and ready for a row
During t
After the command execution, self refresh operation continues while CKE remains low.
During self refresh mode, refresh interval and refresh operation are performed
