Follow the steps below to transmit data using the polled method of operation:
1. Write to the UART Baud Rate High and Low Byte registers to set the required baud
2. Enable the UART pin functions by configuring the associated GPIO port pins for
3. Write to the UART Control 1 register, if MULTIPROCESSOR mode is appropriate, to
4. Set the Multiprocessor Mode Select (MPEN) bit to enable MULTIPROCESSOR mode.
5. Write to the UART Control 0 register to:

Set the transmit enable bit (TEN) to enable the UART for data transmission
Set the parity enable bit (PEN), if parity is appropriate and MULTIPROCESSOR
mode is not enabled, and select either even or odd parity (PSEL).
Set or clear the CTSE bit to enable or disable control from the remote receiver
using the CTS pin.
