CpE390 Lab 3 (Chapter 4 of Textbook) The CML-12S-DP256 is an updated development board with 256KB of memory, a somewhat more advanced development board than the Axiom CME12BC32 described in your textbook. The memory map for the textbook’s CME-12BC is shown and described on page 105 of your textbook. As noted there, “you need to understand the memory map of the . .. demo board in order to be able to download your program to the proper memory space.” The Axiom CML 12S-DP256 is an HC12 evaluation board developed by Axiom Manufacturing ( ), providing 256 kB of memory. Memory maps differ among evaluation boards with different amounts and distributions of memory. When programming for the CML 12S-DP2256, you should be applying the following memory map. I recommend that you use locations $4000-$7FFF for your program and data.
