for filing the report!

the supplied header files from the device manufacturer use the #define form


The keyword "volatile" seems to be missing there then. So f.e. the second "|=" operation would be allowed to use an intermediate result from the first "|=" operation (instead of rereading the port address).

Appart from that they should be equivalent.
