Figures 68 and 69 illustrates the asynchronous data format employed by the UART with-
out parity and with parity, respectively.
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 desired baud
2. Enable the UART pin functions by configuring the associated GPIO Port pins for
3. Write to the UART Control 1 register to enable Multiprocessor (9-bit) mode functions,
4. Write to the UART Control 0 register to:
