        To enable semihost, user must define "DEBUG_ENABLE_SEMIHOST" constant when build code with M071M BSP.
        This sample code is used to show how to print message/getchar on IDE debug environment.
        It will echo all input character back on UART #1 of KEIL IDE.

        In KEIL MDK, user need to open "View->Serial Window->UART #1" windows in debug mode.
        In IAR Workbench, user need to open "View->Terminal I/O" in debug mode.

        NOTE1: HardFault_Handler handler is implemented in retarget.c.
        NOTE2: Semihost only works with Nuvoton NuLink ICE Dongle in debug mode.
        NOTE3: It does not print any message if Nuvoton NuLink ICE Dongle is not connected.
