* @file UART0.h
* @brief Provide receive/transmit functions for EUSCI A0
* @details EUSCI_A0 UART is connected to the PC via the USB cable
* To be able to use printf<br>
* 1) add UART0.c to project<br>
* 2) "..\inc\UART0.h"<br>
* 3) Must be running at 48 MHz, Clock_Init48MHz();<br>
* 4) Call UART0_Initprintf()
* @remark UCA0RXD (VCP receive) connected to P1.2
* @remark UCA0TXD (VCP transmit) connected to P1.3
* @remark Busy-wait device driver for the EUSCI A0 UART
* @version V1.0
