MDN, Maybe it would be appropriate for you to invest in good debugging tools that allow you to actually test your code on the actual silicon rather than attempting to simulate it using a simulator. Using a BDM you can test the peripherals on your target board. Even better but more expensive is a full-emulator, that offers many benefits over a BDM including the ability to test your code on the actual silicon even before you have designed or received your target board. Once you receive the target board, you can plug it to the full-emulator and continue to the next step of your debugging. You can read the following articles to get more details: http://www.nohau.com/products/hcs12_emulator_features.pdf http://www.nohau.com/appnotes/hcs12bdm_emulator.pdf Hope this helps, Doron Nohau Corporation HC12 In-Circuit Emulators www.nohau.com/emul12pc.html At 09:26 AM 8/6/2003 +0000, you wrote: >Thanks for the response, > >Since I have 2-3 weeks to get by EVM thought why not try simulating >some of the MCU peripherals of my interest.
