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.
Reserved. Unknown During Read.
OUT2 function. Controls the TENn output behavior:
1 = TENn is driven by the UART3Flag.BUSY status bit;
that is, TENn is low whenever the UART has transmit data
to send.
0 = TENn is controlled by the OUT1 bit.
OUT1 function. When OUT2 = “0”, then TENn = OUT1.
Otherwise OUT1 is ignored.
