Transmitting Data using the Polled Method  
Follow these steps 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  
rate.  
2. Enable the UART pin functions by configuring the associated GPIO Port pins for  
alternate function operation.  
3. Write to the UART Control 1 register, if MULTIPROCESSOR mode is appropriate, to  
enable MULTIPROCESSOR (9-bit) mode functions.  
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.
