TMS320F280049: consulting LIN communication strategy

Hi expert,

My customer meets a situation where the host will send frame with ID 0x29 and 0x2A in turn with a 200mS interval. At the same time, the host will send frame with 0x28 at 100mS interval. For F280049 acting as a LIN slave and can only receive data by polling, do you have any advice on how should they make this kind of communication without a conflit?

Thanks

Sheldon
