24.12 Programmer’s 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.
