Below is an example of a similar program for the given microcontroller/system this assignment will be performed on. It can be used as a reference if you would like the required addresses for setup, but the main program is what's needed.

Write a c program that receives input from switch 1 and switch 2 , and output to the three LEDs, Red, Green, and Blue. Your program should work like this: Switch 1 pressed and switch 2 released LED Red goes on. Switch 1 released and switch 2 pressed LED Green goes on. Switch 1 pressed and switch 2 pressed LED Blue goes on. Switch 1 released and switch 2 released All LEDs off
