After two interesting posts. The problem is solved.

I have made two method a read and a write. For each register change in
the uart I call this method with the register address. Before I write
the address I write something (0xff) to spr register. After that I
read or write the register with the correct value.

this seems to work for writing to the register I still have a problem
with my ISR ad the moment but it will be solved in a day.
