This is control field data to set the number of bytes of a data field. 0 to 8 can be set.
At reset, these bits are undefined.
These bits set the identifier field.
For standard format (IDFM = 0), the higher 3 bits of the 11 bits are set.
For extended format (IDFM = 1), the higher 3 bits (ID28 to ID26) of the 29 bits (ID28 to
At reset, these bits are undefined.
