Lab Problem 1: Analyze the following code to determine the sequences of lighting of LEDs on the Dragon 12-Plus microcontroller board. Provide the sequences in order and some explanation of why specific LEDs turn ON. In the following code, we are working only with LEDs 21 and 0. Verify the operation of the code by entering CodeWarrior via "Load Example Project" and working with Debug Instruments under "Full Chip Simulation mode.
