Again I came back to the FIFO fill level calculations for SAI. If it is not possible to get the tx/rx FIFO fill level so how it is possible to know it? Lets say SSI has got FIFO counter for that purpose. What can you suggest?

 

Also, could you at least give more brief description about WFP and RFP pointer values in case receive/transmit FIFO is not FULL? Let say receive/transmit FIFO is half full. Do the pointer values differ?
