Do not allow applications to use the full buffer found on McBSP1,3,4,5. Using the full buffer in threshold mode causes the McBSP buffer to run dry, which can be observed as channels are switching (in reality the channels are shifting).

Is it possible that also McBSP2 would require that maximum burst transmit size should be 0x10 smaller than size of internal buffer/fifo?
