M051 半主机调试测试
测试环境：IAR6.20 + Nu-link me + M0516
测试代码：
#include <stdio.h>
#include "DrvUART.h"
#include "DrvGPIO.h"
int main()
{
  STR_UART_T sParam;

  sParam.u32BaudRate             = 115200;
  sParam.u8cDataBits             = DRVUART_DATABITS_8;
  sParam.u8cParity                = DRVUART_PARITY_NONE;
  sParam.u8cStopBits             = DRVUART_STOPBITS_1;
  sParam.u8cRxTriggerLevel       = DRVUART_FIFO_1BYTES;
  sParam.u8TimeOut                = 30;

  DrvUART_Open (UART_PORT0, &sParam);
  DrvGPIO_InitFunction(E_FUNC_UART0);

  printf("Hello!\r\n");

  while(1);
}
M051 不使用半主机调试(默认)
1、NuvotonPlatform_IAR\Src\Driver\retarget.c
//#define DEBUG_ENABLE_SEMIHOST /* To enable semihosted. !!!The SEMIHOSTED of startup_NUC1xx.s must be {TRUE} */
2、CMSIS\CM0\DeviceSupport\Nuvoton\M051Series\startup\iar\ startup_M051Series.s
SEMIHOSTED    SET 0
3、编译结果：
  4 662 bytes of readonly  code memory
130 bytes of readonly  data memory
  1 444 bytes of readwrite data memory
4、运行结果：
