 * AUTHOR: Philip Johansson                                            *
 * PURPOSE: Flip USART inversion on USART0                             *
 * INFORMATION:                                                        *
 * This functionality exists only on USART0.                           *
 * Initialize with the desired value                                   *
 *	                                                                   *
 * GLOBAL VARIABLES:                                                   *
