12.4.3 Transmit Structures
The MSCAN08 has a triple transmit buffer scheme to allow multiple messages to be set up in advance
and to achieve an optimized real-time performance. The three buffers are arranged as shown in
Figure
All three buffers have a 13-byte data structure similar to the outline of the receive buffers (see
12.12 Programmer’s Model of Message
contains an 8-bit “local priority” field (PRIO) (see
