 		 #130664 - is it right like this?
Responding to: ???'s previous message
is it this diagram is acceptable for me to switch on the led on the port 0 by using dip switch at port2 and what is the most approriate code to implement it for my future reference.



R3 is the pull-up resistor (tell me if i'm wrong with the connection)
