Receiver request-to-send. Allows the RTS output to control the CTS input of the transmitting device to
prevent receiver overrun. If both the receiver and transmitter are incorrectly programmed for RTS control,
RTS control is disabled for both. Transmitter RTS control is configured in UMR2n[TxRTS].
0 The receiver has no effect on RTS.
1 When a valid start bit is received, RTS is negated if the UART's FIFO is full. RTS is reasserted when the
If RTS is controlled by the fill level of the receiver FIFO via UACRn[RTSL], this bit should be cleared.

0 RxRDY is the source that generates IRQ.
1 FFULL is the source that generates IRQ.
If more detail on the status of the FIFO is required, UISRn{RxFIFO] indicates a change in the FIFO status
as programmed in URFn[RXS].
Error mode. Configures the FIFO status bits, USRn[RB,FE,PE].
0 Character mode. The USRn values reflect the status of the character at the top of the FIFO. ERR must

Parity mode. Selects the parity or multidrop mode for the channel. The parity bit is added to the transmitted
character, and the receiver performs a parity check on incoming data. The value of PM affects PT, as shown
below.
Parity type. PM and PT together select parity type (PM = 0x) or determine whether a data or address
character is transmitted (PM = 11).
Bits per character. Select the number of data bits per character to be sent. The values shown do not include
start, parity, or stop bits.
