TMS320C6678: Lot trace code information

Part Number:TMS320C6678

Hi,

We have a customer received a package of TMS320C6678ACYPA. 

Customer is confused about the information on device marking and package LOT trace code.

Can you tell us how to read the LOT Trace code from package as well as from device marking?

Thanks.

P.S.
