Dear Experts,
now i am working with TivaC TM4C123GH6PM an energia. i never work in watch dog timer before so i was rewrite the watch dog timer example code(i get code from google) like below,
#include "driverlib/interrupt.h"
#include "driverlib/sysctl.h"
#include "driverlib/watchdog.h"
#include "driverlib/rom_map.h"
#include "driverlib/rom.h"
void setup()
{
Serial.begin(9600);
Serial.println("SETUP");
MAP_SysCtlPeripheralEnable(SYSCTL_PERIPH_WDOG0); // Enable the watchdog peripheral
MAP_WatchdogReloadSet(WATCHDOG0_BASE, MAP_SysCtlClockGet() * 2); // Set
