RXDMABMD=ONE_WORD, RXDMAEN=DISABLED, TXDMAEN=DISABLED, TXDMABMD=ONE_WORD
DMA Control
| TXDMAEN | Transmit DMA Enable. 0 (DISABLED): Disable transmitter DMA data requests. 1 (ENABLED): Enable transmitter DMA data requests. |
| RXDMAEN | Receive DMA Enable. 0 (DISABLED): Disable receiver DMA data transfer requests. 1 (ENABLED): Enable receiver DMA data transfer requests. |
| TXDMABMD | Transmit DMA Burst Mode. 0 (ONE_WORD): The transmitter transmits one word at a time. Whenever there is any room in the transmit FIFO, a single word burst DMA data request is generated. 1 (FOUR_WORDS): The transmitter transmits four words at a time. Whenever the FIFO depth drops below five, a DMA burst request is generated for four words. |
| RXDMABMD | Receive DMA Burst Mode. 0 (ONE_WORD): The receiver receives one word at a time. Whenever there is at least one word in the receive FIFO, a single word burst DMA request is generated. 1 (FOUR_WORDS): The receiver receives four words at a time. Whenever the FIFO depth rises above three, a DMA burst request is generated for four words. |
