 		 #42579 - RE: Using P2 and external RAM - Pranav
Responding to: ???'s previous message
As I mentioned in my original post (and Raghu pointed out two messages ago) I just want to read the DIP switch *once*, when the system is booting up. There will be no code in any external memory. I am in fact using an 8155 chip to do this. This is a one-time only progrect, using parts that I have on hand.

So to reiterate my original question, is it ok if I simply read the DIP switch on P2 once at start up and without using any MOVX instructions in that part of the code? If it is ok, then I would be best off using the DIP switch to pull a pullup to ground?

Thanks!
