The McASP can generate one DMA request to the DMA_CROSSBAR to transmit (MCASPi_DREQ_TX) or receive (MCASPi_DREQ_RX) data. A DMA request to transmit data is generated if the XDATDMA bit in the MCASP_XEVTCTL register is cleared. A DMA request to receive data is generated if the RDATDMA bit in the MCASP_REVTCTL register is cleared.
