Ok but IFS definitely needs to be set. EIFS I'm not entirely sure about, haven't looked at the timing diagrams for a long time. > Note that the fact that the IFS is set twice for rt2500usb might suggest the > documentation for the register is incorrect and perhaps the purpose of the > register is completely different.

That won't be easy to tell, but the IFS is different afaik so there the mode has an influence. But I think that this mode setting need not be tied to the frequency table. johannes
