Hi Jan, Oops, I had an error in my debug code. Sorry for that. The status value is actually 0x0050 and not 0xb70f. The regular status values are 0x4050, 0x0050, 0x2050, That seems to be ok as well... One thing, I have just looked at: The driver uses the Early Interrupt (ER) Flag for signaling. Can this be, that the interrupt comes in, the ER is signaled but the data is not yet available?!? How is this handled by the driver - or this is not relevant?
