the code below is what needs to be adjusted for the program to function and it's the only thing I need thank you!

; GPIO.s

; Runs on LM4F120 and TM4C123

; Implements a NOT gate described in class

; PD3 is an output to LED, Positive logic

; PD0 is an input from switch, Positive logic

; Switch pressed causes LED to go OFF and

; release causes LED to go ON.

; **** To run this example in Simulator

; make sure and copy the C0DLL.dll file

;(in the folder where this [GPIO.s]file is)

; to your Keil ARM/Bin folder;

;; Note that running the simulator gives 4 warnings

;; Click OK and continue

made ln lab.) (5 pts) (a) Design a system that uses Port D pins 1, 2, 4, 5, 6. Pins 1 is input and Pins 2, 4, 5 and 6 are outputs. When the program starts, LEDs 2 and 5 turn on, LEDs 4 and 6 turn off toggle so LEDs 2 and 5 turn off, LEDs 4 and 6 turn on, in one cycle (loop). Then system repeats this process forever. Even though input pin is initialized, it's not used. (15pts) (b) After building the system, can you see if LEDs are toggling? Use no more than three sentences explain. 2. . Then all LEDs You must bring your circuit, code and working system to instructor to check. If all parts are correct, you pass Part
