The Dynamic Memory Self-refresh Exit Time register allows you to program the self- refresh exit time, tSREX. It is recommended that this register be modified during system initialization, or when there are no current or outstanding transactions. Wait until the memory controller is idle, then enter low-power or disabled mode. This value normally is found in SDRAM data sheets as tSREX.

Note: The Dynamic Memory Self-refresh Exit Time register is used for all four dynamic memory chip selects. The worst case value for all chip selects must be programmed.

The Dynamic Memory Last Data Out to Active Time register allows you to program the last-data-out to active command time, tAPR. It is recommended that this register be modified during system initialization, or when there are no current or outstanding transactions. Wait until the memory controller is idle, then enter low- power or disabled mode. This value normally is found in SDRAM datasheets as tAPR.

Note: The Dynamic Memory Last Data Out to Active Time register is used for all four dynamic memory chip selects. The worst case value for all chip selects must be programmed.
