I can't find these functions/macros, but I think you mean the 
write{b,s,l} macros. As I already indicated in a previous e-mail, they 
do not work in my code. If I replace, e.g. the PUT32 with writel than 
the code doesn't run. I will look into that problem after I've finished 
another project at work.

Kind regards,
