Universal Asynchronous Receivers/Transmitters (UARTs)
With the BRD values available, the UART configuration is written to the module in the following order:
1. Disable the UART by clearing the UARTEN bit in the UARTCTL register.
2. Write the integer portion of the BRD to the UARTIBRD register.
3. Write the fractional portion of the BRD to the UARTFBRD register.
4. Write the desired serial parameters to the UARTLCRH register (in this case, a value of 0x0000.0060).
5. Optionally, configure the µDMA channel and enable the DMA options in the UARTDMACTL register.
6. Enable the UART by setting the UARTEN bit in the UARTCTL register.
