3. Write an interrupt based program that will turn ON/OFF one LED (LED 0) every time a switch connected to P3.2 is closed-opened 5 times. For example, assuming an initially OFF LED, if the user close and open the switch 5 times, the LED turns ON. If the switch is closed-then-opened another 5 times, it will be turned OFF and so on. Your program should not check switch P3.2 status directly (i.e., don't use somthing like JB P3.2)
