在z-stack中開啓看門狗

1 使能WDT_IN_PM1

2 在main函數的下面位置處開啓

#ifdef WDT_IN_PM1
  /* If WDT is used, this is a good place to enable it. */
  WatchDogEnable( WDTIMX );
  //設置開門模式，間隔1s
  WDCTL = 0x00;
  WDCTL = 0x08;
#endif

3 在主循環中喂狗

  for(;;)  // Forever Loop
#endif
  {
    osal_run_system();
    //喂狗
    WDCTL = 0xA0;
    WDCTL = 0x50;
  }
