TMS320C6657: Access control to external memory

Part Number: TMS320C6657

Hi Team,

My customer has a data corruption issue at read timing of memory connected EMIF.
Now, we are breaking down the issue into parts and I have following two questions on TMS320C6657CZH25 to eliminate one of possibility.
1. Does TMS320C6657CZH25 have a built in function that prevents two cores from accessing EMIF at the same time, like prioritized access control?
2. If yes, Could you tell me how to set to utilize the function?

Regards,
