Question

In MPLAB XIDE create a program using assembly to produce three different LED combinations using 4 LED lights and 4 switches that correspond to each LED. There will be 4 inputs and 4 outputs. The program includes three levels (the three LED combinations). Each level will be a random combination (i.e. red, blue, green, orange). The player will then repeat the combinations as accurately as possible. If the player repeats the led sequence correctly, the code will branch to the next set of outputs the player moves to the next level). If the user repeats the LED sequence incorrectly all LEDs will turn on, all LEDs are clear and the game restarts the code will branch back to the beginning, which restarts the game. Here is the template
