Hi I'm just started a couple of weeks ago with assembly, but now I don't know how to read just 1 pin and don't look at the other pins.
I want to use PA3 as an high low input and PB0 and PB1 as output.
This is what I made so far:
;*** selection of the setting ***
But now I look at all the pins of register A and I only want to look at pin PB3. I don't know how to do that. I thought that it was possible read PINA3 but this is not working.
I read something about masking but I'm not sure that I can use this.
Is it possible to do something like that and what do I do wrong?
