Memory Map
The MSCAN08 occupies 128 bytes in the CPU08 memory space. The
absolute mapping is implementation dependent with the base address
being a multiple of 128.

ProgrammerÕs Model of Message Storage
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.
