Figure 15. Transmit Buffer Identifier Register (TBI)
ID10 – ID3 — Identifier bits
The identifier consists of 11 bits (ID10 – ID0). ID10 is the most
significant bit and is transmitted first on the bus during the arbitration
procedure. The priority of an identifier is defined to be highest for the
smallest binary number. The three least significant bits are contained
in the TRTDL register. The seven most significant bits must not all be
recessive.
