The msCAN12 has a triple transmit buffer scheme in order 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
additional transmit buffer priority register (TBPR) contains an 8-bit so
