Pubesh,
thanks for your hints. Yes, I know these sections, but in my experience this is not true when the AFIFO is in use. So when the AFIFO is in use, the XUNDRN and ROVRN bits will never ever get set.
I speculate that the AFIFO feeds the McASP with data even when it has run empty, and that this prevents the XUNDRN and ROVRN bits from getting set.
And on the other hand, I did not find any UNDRN or OVRN bits for the AFIFO itself, so I think an overrun/underrun of the AFIFO itself is not reported.
Do you agree to this analysis ?
Any idea on how to get around this ?
Thanks and best regards,
Christoph
