SPI DMA control register
| TX_DMA_GO | Transmit DMA start Set this bit to 1 will start the transmit DMA process. SPI module will issue request to DMA module automatically. If using DMA mode to transfer data, remember not to set GO_BUSY bit of SPI_CNTRL register. The DMA controller inside SPI module will set it automatically whenever necessary. Hardware will clear this bit automatically after DMA transfer done. |
| RX_DMA_GO | Receive DMA start Set this bit to 1 will start the receive DMA process. SPI module will issue request to DMA module automatically. Hardware will clear this bit automatically after DMA transfer done. |
