2.5 to 3.3 V UART with 128-byte FIFOs and IrDA encoder/decoder
7.20 RS-485 Turn-around time delay (RS485TIME)
The value in this register controls the turn-around time of the external line transceiver in
bit time. In automatic 9-bit mode RTS or DTR pin is used to control the direction of the line
driver, after the last bit of data has been shifted out of the transmit shift register the UART
will count down the value in this register. When the count value reaches zero, the UART
will assert RTS or DTR pin (logic 0) to turn the external RS-485 transceiver around for
receiving.

AFCR2[5]
RTSInvert. Invert RTS or DTR signal in automatic 9-bit mode.
logic 0 = RTS or DTR is set to 0 by the UART during transmission,
and to 1 during reception
logic 1 = RTS or DTR is set to 1 by the UART during transmission,
and to 0 during reception
AFCR2[4]
RTSCon. Enable the transmitter to control RTS or DTR pin in
automatic 9-bit mode.
logic 0 = transmitter does not control RTS or DTR pin
logic 1 = transmitter controls RTS or DTR pin
AFCR2[3]
RS485 RTS/DTR. Select RTS or DTR pin to control the external
transceiver.
logic 0 = RTS pin is used to control the external transceiver
logic 1 = DTR pin is used to control the external transceiver
AFCR2[2]
TXDisable. Disable transmitter
logic 0 = transmitter is enabled
logic 1 = transmitter is disabled
AFCR2[1]
RXDisable. Disable receiver
logic 0 = receiver is enabled
logic 1 = receiver is disabled
AFCR2[0]
9-bitMode. Enable 9-bit mode or Multidrop (RS-485) mode
logic 0 = normal RS-232 mode
logic 1 = enable 9-bit mode
