The UART Transmitter interrupt indicates the availability of the Transmit Data register to
accept new data for transmission. Follow the steps below to configure the UART for
interrupt-driven data transmission:
1. Write to the UART Baud Rate High and Low Byte registers to set the appropriate baud
2. Enable the UART pin functions by configuring the associated GPIO port pins for
