MPRX—Multiprocessor Receive
This status bit is for the receiver and reflects the actual status of the last multiprocessor bit
received. Reading from the UART Data register resets this bit to 0.
UARTx Control 0 and Control 1 Registers
The UARTx Control 0 and Control 1 registers (Tables 54 and 55) configure the properties
of the UART’s transmit and receive operations. The UART Control registers must ben be
written while the UART is enabled.

TEN—Transmit Enable
This bit enables or disables the transmitter. The enable is also controlled by the CTS signal
and the CTSE bit. If the CTS signal is low and the CTSE bit is 1, the transmitter is
enabled.
0 = Transmitter disabled.
1 = Transmitter enabled.
REN—Receive Enable
This bit enables or disables the receiver.
0 = Receiver disabled.
1 = Receiver enabled.
