Im using an EVB9S12NE64 with codewarrior v6.1, build 6037. I am attempting to drive LEDs using port B but cannot seem to change the portB value. I am programming in assembly and would think simply loading an accumulator and storing the accumulator value to PortB would suffice although no state change is observered. Does anyone have a sample code or other suggestions?
