Details

Multiple Tx Buffers are configured with the same Message ID. Transmission of these Tx buffers is requested sequentially in ascending order with a delay between the individual Tx requests. Depending on the delay between the individual Tx requests, the Tx Buffers may not be transmitted in the expected ascending order of the Tx Buffer number.

Workarounds

First, write the group of Tx messages with same Message ID to the Message RAM. Then, request transmission of all of these messages concurrently by a single write access to TXBAR.

Use the Tx FIFO instead of dedicated Tx Buffers for the transmission of several messages with the same Message ID in a specific order.
