Receive DMA Start
Set this bit to 1 will start the receive PDMA process. SPI controller will issue
request to PDMA controller automatically.
Hardware will auto clear this bit to 0 after PDMA function done.
Transmit DMA Start
Set this bit to 1 will start the transmit PDMA process. SPI controller will issue
request to PDMA controller automatically.
If using PDMA mode to transfer data, remember not to set GO_BUSY bit of
SPI_CNTRL register. The DMA controller inside SPI controller will set it
automatically whenever necessary.
Hardware will auto clear this bit to 0 after PDMA function done.
Note: In DMA mode, the burst mode is not support.
