Exercise: Toggle the two PORTA LSB bits $($D$2$ & D$3)$ if the switch S$1$ connected to

RB$4$ is ON; else, toggle the two MSB bits $($D$4$ & D$5).$ Use TMR$0$ library function

to generate the time delay.

$1.$ Check the configuration setting is correct in $$System Module$.$

$2.$ Generate the code.

$3.$ Click main.c and modify the code in the main program space to interact

with the input.

$4.$ Build and download the code to the curiosity board and test the

function.

You will interact with the input by using $$Getvalue$.$ Partial code below

#include $"$mcc$\_$generated$\_$files$/$mcc$.$h$"$

void myISR$($void$)$;

volatile int currentIndex;

void main$($void$)$
