2. Not applicable for receive buffers
Figure 21-10. Message Buffer Organization
21.13.1 Message Buffer Outline
Figure 21-11 shows the common 13-byte data structure of receive and
transmit buffers for extended identifiers. The mapping of standard
identifiers into the IDR registers is shown in Figure 21-12. All bits of the
13-byte data structure are undefined out of reset.
NOTE: The foreground receive buffer can be read anytime but cannot be
written. The transmit buffers can be read or written anytime.
