Advisory

During DCAN FIFO Mode, Received Messages May be Placed Out of Order in the FIFO Buffer

Revisions Affected

B, C

Details

In DCAN FIFO mode, received messages with the same arbitration and mask IDs are supposed to be placed in the FIFO in the order in which they are received. The CPU then retrieves the received messages from the FIFO via the IF1/IF2 interface registers. Some messages may be placed in the FIFO out of the order in which they were received. If the order of the messages is critical to the application for processing, then this behavior will prevent the proper use of the DCAN FIFO mode.

Workarounds

None
