NOTE:
This section details the organization of the receive and transmit
message buffers and the associated control registers. For reasons of
programmer interface simplification, the receive and transmit message
buffers have the same outline. Each message buffer allocates 16 bytes
in the memory map containing a 13-byte data structure. An additional
transmit buffer priority register (TBPR) is defined for the transmit buffers.

transmit buffers for extended identifiers. The mapping of standard
identifiers into the IDR registers is shown in
13-byte data structure are undefined out of reset.
The foreground receive buffer can be read anytime but cannot be
written. The transmit buffers can be read or written anytime.
