        To enable semihost, user must define "DEBUG_ENABLE_SEMIHOST" constant when build code with M051Series 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 when semihost enabled.

        NOTE2: Semihost only works with Nuvoton NuLink ICE Dongle.
