There is three types of SDRFC value in the "Registers" sheet. What are these differences? How are these used for the SDRFC Configuration?

Hi,
DDR_SDRFC (normal) -> We have to use this value for normal operation i.e after DDR initialization done.
DDR_SDRFC (ext_temp) -> We have to use this value for extended temperature devices.
DDR_SDRFC (initialization) -> We have to use this value while DDR initialization.

Please refer to gel file.
C:\ti\ccsv5\ccs_base\emulation\boards\evmc6678l\gel\evmc6678l.gel

Where do you want to use this register ?
