Functional Description
41.4.2.2.2 Local Priority enabled
If Local Priority is desired MCR[LPRIO_EN] must be asserted. In this case the Mailbox
PRIO field is included at the very left of the arbitration value (see the following table).
As the PRIO field is the most significant part of the arbitration value Mailboxes with low
PRIO values have higher priority than Mailboxes with high PRIO values regardless the
rest of their arbitration values.
Note that the PRIO field is not part of the frame on the CAN bus. Its purpose is only to
affect the internal arbitration process.
41.4.2.3 Arbitration Process (continued)
Once the arbitration winner is found, its content is copied to a hidden auxiliary MB called
Tx Serial Message Buffer (Tx SMB), which has the same structure as a normal MB but is
not user accessible. This operation is called “move-out” and after it is done, write access
to the corresponding MB is blocked (if the AEN bit in MCR is asserted). The write
access is released in the following events:
At the first opportunity window on the CAN bus, the message on the Tx SMB is
transmitted according to the CAN protocol rules. FlexCAN transmits up to eight data
bytes, even if the DLC (Data Length Code) field value is greater than that.
