Self-refresh exit:
When this command is executed during self-refresh mode, the SDRAM module can exit
from self-refresh mode. After exiting from self-refresh mode, the SDRAM module enters the IDLE state.
Power down exit:
When this command is executed at the power down mode, the SDRAM module can exit
from power down mode. After exiting from power down mode, the SDRAM module enters the IDLE state.
Function Truth Table
The following table shows the operations that are performed when each command is issued in each mode of
the SDRAM module. The following table assumes that CKE is high.
