MSCAN Controller
18.12 Programmer’s Model of Message Storage
Technical Data
346
The following 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.
