How do I specify doubling of the refresh rate in High Performance DDR/DDR2 Controller when DDR/DDR2 memory is operating over extended temperature range?

Environment

Description

You can modify the trefi parameter in the DDR/DDR2 Megawizard® by clicking on Modify parameters. This would make the controller issue the refreshes at the interval specified by the trefi parameter.

You can also turn the user controlled refresh option ON to have the control over refresh operation.
