Universal Asynchronous Receive Transmit controls for use with printf and other stdio functions.

Example Hardware and Register setup:

  // *******************************************************************************
  // Initialize UART0 for printf function
  // *******************************************************************************
  U0LCR=0x83;  // DLAB=1
  U0DLL=32;
  U0DLM=0;
  U0FCR|=1;    // FIFO
  U0LCR=0x3;   // DLAB=0
  PINSEL0_bit.P0_0 = 1;    // UART0 TXD
  PINSEL0_bit.P0_1 = 1;    // UART0 RXD
