RA3 won't get a high level.

[selbstdual]

I used another one and the same result.

This pin is not connected yet so outer components don't interfere.

Here's the whole code. It is a POT command replacement that fits to my circuit (RC = 420 µs). Normally Wert is replaced by Wert2's contents.

If you are not german, you should understand it anyway(Wert means value, Zaehler = counter, Gelb = yellow and Gruen = green)...
