Description
Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
DMA on Error
If this bit is set to 1, DMA receive requests are automatically disabled
when a receive error occurs.
Transmit DMA Enable
If this bit is set to 1, DMA for the transmit FIFO is enabled.
Receive DMA Enable
If this bit is set to 1, DMA for the receive FIFO is enabled.
