Receiver request-to-send. Allows the UnRTS output to control the UnCTS input of the
transmitting device to prevent receiver overrun. If both the receiver and transmitter are
incorrectly programmed for UnRTS control, UnRTS control is disabled for both. Transmitter
RTS control is configured in UMR2n[TxRTS].
0 The receiver has no effect on UnRTS.
1 When a valid start bit is received, UnRTS is negated if the UART's FIFO is full. UnRTS is

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.
1 Block mode. The USRn values are the logical OR of the status for all characters reaching
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.
