23.3.1
The UMR1n registers control UART module configuration. UMR1n can be read or written when the mode
register pointer points to it, at RESET or after a
UCRn[MISC]. After UMR1n is read or written, the pointer points to UMR2n.

Receiver request-to-send. Allows the URTSn output to control the UCTSn input of the transmitting device to prevent
receiver overrun. If the receiver and transmitter are incorrectly programmed for URTSn control, URTSn control is
disabled for both. Transmitter RTS control is configured in UMR2n[TXRTS].
0 The receiver has no effect on URTSn.
1 When a valid start bit is received, URTSn is negated if the UART's FIFO is full. URTSn is reasserted when the
Receiver interrupt select.
0 RXRDY is the source generating interrupt or DMA requests.
1 FFULL is the source generating interrupt or DMA requests.
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 be 0 for
1 Block mode. The USRn values are the logical OR of the status for all characters reaching the top of the FIFO since
Parity mode. Selects the parity or multidrop mode for the UART. 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.
