Reserved. Unknown During Read.
RX DMA error handing enable. If 0, the RX DMA interface
ignores error conditions in the UART receive section. If 1,
the DMA interface stops and notifies the DMA block when
an error occurs. Errors include break errors, parity errors,
and framing errors.
TX DMA interface enable. Setting to 1 enables the private
DMA interface to the transmit FIFO.
RX DMA interface enable. Setting to 1 enables the private
DMA interface to the receive FIFO.
