I am a collage student just starting to work with Freescale. Currently I´m programming in assembler in a HC08AP16 uC. I´m trying to implement a program in the uC, but for some reason is not working. It seems as if it automatically resets itself. So I decided to simulate it directly from the uC. I start the process by doing single steps, but then like at the 10th instruction, the following error shows: "Unable to go into background mode" It says that the Reset was caused by External reset pin. But that is imposible, because the reset pin has nothing connected to it.
And no matter what I do to the program, I keep getting the same error. And it always happens to be at the beginning of the program.
I really cannot find my way around this problem.............any suggestions?
