I am handling SAI audio interface on imx6. There is a SAI Transmit FIFO reg (TFR) with WFP and RFP pointers for transmit data channel. At what condition WFP and RFP pointers are reset to 0?

 

In the reference manual WFP is incremented after each valid write to TDR. Does the WFP is incremented until max value 2^6?
