Issue about S12MSCANV3: Error frame when received message DLC is 15

hi All

we met one issue about this controller issue in the MC9S12XS256.

when the received message DLC is 15,why this controller can not work? It will send out the TxErr and NAK error frame. and will stop sending our App message.

but if change the receieved message DLC to 14, it can work again.

we can confirm that there is no issue in our CAN driver code.

Hoping your good answers!



Best wishes
