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,
