Question: If I plan to use the bootloader in my application, but I am currently in the debugging phase, should I come up in microprocessor mode or microcomputer mode to use the XDS510? I am planning to download my program with the XDS510 load command.

Answer: To use the XDS510 for debugging, you want the device to be in micro-processor mode. If you come up in micro-computer mode and the bootloader starts running its program, the XDS510 has a difficult time trying to regain control of the device, and its operation from that point is unpredictable. The easiest way to implement this is with a jumper that can be set to the MP\MC pin so that you can choose either mode. When you are ready for production boards, design without the jumper.
