The Mailbox Control handles the following functions:
• For received messages, compare the IDs and generate appropriate RAM addresses/data to store
• To transmit messages, RCAN-ET will run the internal arbitration to pick the correct priority
• Arbitrates Mailbox accesses between the CPU and the Mailbox Control.
• Contains registers such as TXPR, TXCR, TXACK, ABACK, RXPR, RFPR, UMSR and

This block conforms to the requirements for a CAN Bus Data Link Controller which is specified
in Ref. [3, 5]. It fulfils all the functions of a standard Data Link Controller as specified by the OSI
7 Layer Reference model. This functional entity also provides the registers and the logic which are
specific to a given CAN bus, which includes the Receive Error Counter, Transmit Error Counter,
the Bit Configuration Registers and various useful Test Modes. This block also contains functional
entities to hold the data received and the data to be transmitted for the CAN Data Link Controller.
