   The mailbox numbers are shared between CAN Transmit and CAN Receive
   blocks with the same CAN port (module) parameter.
 
-  The order in which the messages are transmitted depends on their mailbox numbers.
-  The lower the mailbox number is, the higher is the priority of the message and the
-  sooner will it be transmitted. If you want to have the priority of the messages
-  under control, you have to specify the numbers of the mailboxes manually.

   In order to use this block, there must be a `CAN Configure` block in the model.
