8.15 Receiver FIFO Level register (RXLVL)
8.16 Extra Features Control Register (EFCR)
This register is a read-only register, it reports the fill level of the receive FIFO. That is, the
number of characters in the RX FIFO.

Description
reserved
invert RTS signal in RS-485 mode

reserved
transmit pin, but the transmit FIFO will continue to receive data from
host until full. Any data in the TSR will be sent out before the
transmitter goes into disable state.
Disable receiver. UART will stop receiving data immediately once this
bit set to a 1, and any data in the TSR will be sent to the receive FIFO.
User is advised not to set this bit during receiving.
IrDA mode
Disable transmitter. UART does not send serial data out on the
Enable 9-bit or Multidrop mode (RS-485).
0 = IrDA SIR,
0: RTS = 0 during transmission and RTS = 1 during reception
1: RTS = 1 during transmission and RTS = 0 during reception
0 = transmitter does not control RTS pin
1 = transmitter controls RTS pin
0: transmitter is enabled
1: transmitter is disabled
0: receiver is enabled
1: receiver is disabled
0: normal RS-232 mode
1: enables RS-485 mode
