22.4.2 Mail box
Mailboxes function as message buffers to transmit/receive CAN frames. Each Mailbox is
comprised of four identical storage fields: 1) Message Control, 2) Message Data, 3) Time Stamp
and 4) Local Acceptance Filter Mask. Table 22.2 shows the address map for the control, data,
timestamp and LAFM address for each mailbox.
