The message objects can be configured only through the interface registers; the software does not have direct access to the message object (message RAM) . Familiarize yourself with the interface register set (IFx) usage (see Section 26.10.4.10, Message Interface Register Sets) and the message object structure (see Section 26.10.4.11, Message RAM) before configuring the message objects.
For more information regarding the procedure to configure the message objects, see Section 26.10.4.7, Configuration of Message Objects Description. All the message objects should be configured to particular identifiers or set to not valid before the message transfer is started. It is possible to change the configuration of message objects during normal operation (that is between data transfers).
The message objects initialization is independent of the bit-timing configuration.
