Identifier registers
(IDRn)
The identifiers consist of either 11 bits (ID10–ID0) for the standard, or
29 bits (ID28–ID0) for the extended format. ID10/28 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.
