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 desired baud
2. Enable the UART pin functions by configuring the associated GPIO Port pins for
3. If MULTIPROCESSOR mode is desired, write to the UART Control 1 register to
4. Write to the UART Control 0 register to:
