TMS320DM368: change DDR clock from 243MHZ to other setting (e.g. DDR400(clock=200)、DDR266(clock=133))

Hi,

My customer is using TMS320DM368 EVM as reference design.

And the DDR clock  is 243 Mhz for DDR486 but it cause interference due to the UHF Freq. is also 243MHz.

They want to change DDR clock from 243MHZ to other setting(e.g. DDR400(clock=200)、DDR266(clock=133)).

Please help to check how to change the setting and provide the related info of register or library.

Thanks.
