Other functions of the ENUR register include saving the ninth bit received in the data frame, enabling or
disabling the USART's attention mode of operation and providing additional receiver/transmitter status
information via RCVG and XMTG bits. The determination of an internal or external clock source is done by
the ENUI register, as well as selecting the number of stop bits and enabling or disabling transmit and
receive interrupts. A control flag in this register can also select the USART mode of operation:
asynchronous or synchronous.

5.13.1 USART CONTROL AND STATUS REGISTERS
The operation of the USART is programmed through three registers: ENU, ENUR and ENUI.
