Break Error.
Parity Error.
Framing Error.
The UART IP only implements 16 and 8-bit registers, so the top 2 or 3 bytes of every 32-bit register are
always unavailable.
This bitfield is reserved.
Reserved, do not modify, read as zero.
Ring Indicator. This bit is the complement of the UART ring indicator (nUARTRI) modem status input. That
is, the bit is 1 when the modem status input is 0.
Transmit FIFO Empty. The meaning of this bit depends on the state of the FEN bit in the LCR_H 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.
Transmit FIFO Full.
