No, keep it as it is. My version was just emitting the semaphore using the FW instead of programming the regs directly. This is actually the documented way how to do it, but IIRC we had problems with this and so we are using the direct way ever since shortly after releasing it. No need to switch it back without a good reason, that could just cause trouble. Christian. > > Alex > >> Christian. >> >>> Alex >>
