Mailboxes play a role as message buffers to transmit / receive CAN frames. Each Mailbox is
comprised of 3 identical storage fields that are 1): Message Control, 2): Local Acceptance Filter
Mask, 3): Message Data. The following table shows the address map for the control, LAFM, data
and addresses for each mailbox.
Mailbox-0 is a receive-only box, and all the other Mailboxes can operate as both receive and
transmit boxes, dependant upon the MBC (Mailbox Configuration) bits in the Message Control.
The following diagram shows the structure of a Mailbox in detail.
