share一个看门狗的例程给你吧：

void InitWatchDog(void)
{
SysCtlPeripheralEnable(SYSCTL_PERIPH_WDOG0);
WatchdogReloadSet(WATCHDOG0_BASE, SysCtlClockGet());
WatchdogResetEnable(WATCHDOG0_BASE);
WatchdogStallEnable(WATCHDOG0_BASE);
WatchdogEnable(WATCHDOG0_BASE);
}

void FeedDog(void)
{
WatchdogReloadSet(WATCHDOG0_BASE, SysCtlClockGet());
}
