19.4 ECAN Message Buffers
ECAN Message Buffers are part of DMA RAM Memory.
They are not ECAN special function registers. The user
application must directly write into the DMA RAM area
that is configured for ECAN Message Buffers. The
location and size of the buffer area is defined by the
user application.
