Reserved. Unknown During Read.
Transmit FIFO Empty. The meaning of this bit depends on
the state of the FEN bit in the UART3LinCtrlHigh register.
If the FIFO is disabled, this bit is set when the transmit
holding register is empty. If the FIFO is enabled, the TXFE
bit is set when the transmit FIFO is empty.
Receive FIFO Full. The meaning of this bit depends on the
state of the FEN bit in the UART3LinCtrlHigh register. If
the FIFO is disabled, this bit is set when the receive
holding register is full. If the FIFO is enabled, the RXFF bit
is set when the receive FIFO is full.
