Hey everyone, new here. I am currently doing an assignment to write a program in assembly for the MC68HC11 microcontroller using the HCSim11 simulator. The program must make use of the IRQ request line. On Strobe A rising edge, a count from 0 to a set maximum (the maximum is set by switches PC0 - PC4) will begin and display the numbers on the LCD screen. Now, I know pretty much how to do this. I had the program working and all, but I made some changes according to the assignment guidelines and now I get an error. The program waits for an interrupt, and when I switch strobe A on, i get a warning: "The PC is placed on an address outside the list window. The disassembler window is made active so you can still trace the program counter." I have retraced steps, followed examples and I cannot figure out how to fix this, let alone what it means. Any help would be great, seeing as people in my course, including instructors, are not offering any. Googleing has been fruitless.
