22.13 Programmer’s Model of Message Storage
MC68HC08QA24
Freescale Semiconductor
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.
