lesson 3
ok i got this....as i did the changing of the numbers from 0 to 3. It was obvious that those numbers represents binary numbers of the portc and corresponds to LED1 and LED2(assigned via software)
completely missing the point that:-
portc pins 0 and 1 are shorted to ground and will always be at logic zero level.
latc always reads back as the last value written to it [even when port is set as input ]
latc does not represent the logic level as applied to the pins


I would love if you could explain to me were this could be useful in real life.
if you don't know how it works how can you use it ?
