Or I just try to figure out how changes the speed of a running program if I modify values of these elements.
I am not sure how the resistor is set the frequency itself. This resistor and capacitor works like an oscillator? As I can remember (and Googled) this system is not oscillating - or may I am wrong?

Thanks for any hints!
