design interfacing circuit and alp using any MC or MP for following three locations loc1,loc2,loc3 are two bit locations having all 00 . but increments one last per second of time which goes to 0 again after next clock starts i.e., is increments till 24*60*60-1 ,we need assume specific time for specific values of loc1,loc2,loc3.and we need to glow the 8 LED's according to hours ,minutes,seconds in binary format and we also need to glow another three LEDs for hour minute and second
