SDRAM access request occurs again, the clock is automatically restarted.
When no SDRAM access request is present and the command FIFO of the memory
controller becomes empty, the SDRAM can be placed into Powerdown mode by
automatically disabling CKE after the number of clock cycles specified in the
power_down_prd field. When an SDRAM access request occurs again, CKE is
automatically enabled to exit the Powerdown mode.
These bits set the row and columun addresses. Selectable maximum memory size is 512
Mbytes.
