RXFIW=ONEFRAME, CTSEN=DISABLE, CTSINV=DISABLE, RTSINV=DISABLE, TXFIW=ONEFRAME, RTSRXFW=ONEFRAME, DBGHALT=DISABLE
No Description
| DBGHALT | Debug halt 0 (DISABLE): Continue normal UART operation even if core is halted 1 (ENABLE): If core is halted, receive one frame and then halt reception by deactivating RTS. Next frame reception happens when the core is unhalted during single stepping.  |  
| CTSINV | Clear-to-send Invert Enable 0 (DISABLE): The CTS pin is active low 1 (ENABLE): The CTS pin is active high  |  
| CTSEN | Clear-to-send Enable 0 (DISABLE): Ignore CTS 1 (ENABLE): Stop transmitting when CTS is inactive  |  
| RTSINV | Request-to-send Invert Enable 0 (DISABLE): The RTS pin is active low 1 (ENABLE): The RTS pin is active high  |  
| TXDMAWU | Transmitter DMA Wakeup  |  
| RXDMAWU | Receiver DMA Wakeup  |  
| SFUBRX | Start Frame Unblock Receiver  |  
| RXPRSEN | PRS RX Enable  |  
| TXFIW | TX FIFO Interrupt Watermark 0 (ONEFRAME): TXFL status flag and IF are set when the TX FIFO has space for at least one more frame. 1 (TWOFRAMES): TXFL status flag and IF are set when the TX FIFO has space for at least two more frames. 2 (THREEFRAMES): TXFL status flag and IF are set when the TX FIFO has space for at least three more frames. 3 (FOURFRAMES): TXFL status flag and IF are set when the TX FIFO has space for at least four more frames.  |  
| RXFIW | RX FIFO Interrupt Watermark 0 (ONEFRAME): RXFL status flag and IF are set when the RX FIFO has at least one frame in it. 1 (TWOFRAMES): RXFL status flag and IF are set when the RX FIFO has at least two frames in it. 2 (THREEFRAMES): RXFL status flag and IF are set when the RX FIFO has at least three frames in it. 3 (FOURFRAMES): RXFL status flag and IF are set when the RX FIFO has four frames in it.  |  
| RTSRXFW | Request-to-send RX FIFO Watermark 0 (ONEFRAME): RTS is set if there is space for at least one more frame in the RX FIFO. 1 (TWOFRAMES): RTS is set if there is space for at least two more frames in the RX FIFO. 2 (THREEFRAMES): RTS is set if there is space for at least three more frames in the RX FIFO. 3 (FOURFRAMES): RTS is set if there is space for four more frames in the RX FIFO.  |
