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.

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].

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).
