Hi guys,
thank you very much for your fast replies!
@robtillaart:
the output of "my" code looks like this:

sometimes it reads 011111111111111111..... and sometimes there are bits like narrow: 010101010100011.....
but they are all starting with a zero.
@el_supremo:
Your comment sounds good. I tested it, but it gives me just 000...
Here is the output of a few sample reads:

It seems to go in the right direction, but there must still be a mistake in because in case of a correct reading the PAT0 bit of the status byte should be 1. So the result can't be correct.
Thank you very much so far!
