Thanks for your tips and hints vgs.

I have tried what you told me but have problems to changes the frame properly. I want do do it after the "end of frame" interrupt is being fired, but can't figure out how I can access it. Does anybody have experience with that?

The documentation says about the interrupt register:

"Bit 1 of this register is the end of frame interrupt bit. All other bits are unused. Writing a 1 to bit 1 resets the end of frame interrupt."

- "Bit 1": is this the first bit, or the second one (with the first one being Bit 0) ? I guess the first one.

- I know now how to reset it, but do I read it? Is it the first bit with a rising edge, when the documentation says "firing"? And do I have to reset it manually?
