int toggle;
void timer_B_0_Int(void)
{
	TimerIntClear(TIMER0_BASE, TIMER_TIMB_TIMEOUT);
	toggle ^=0x00000002;
	 GPIOPinWrite(GPIO_PORTF_BASE, GPIO_PIN_1, toggle);


}


int main(void)
{
	 SysCtlClockSet(SYSCTL_SYSDIV_10 | SYSCTL_USE_PLL | SYSCTL_OSC_MAIN | SYSCTL_XTAL_16MHZ);
	 SysCtlPeripheralEnable(SYSCTL_PERIPH_GPIOF);
	 GPIOPinTypeGPIOOutput(GPIO_PORTF_BASE, GPIO_PIN_3|GPIO_PIN_2|GPIO_PIN_1);
	 SysCtlPeripheralEnable(SYSCTL_PERIPH_TIMER0);

	 TimerClockSourceSet(TIMER0_BASE,TIMER_CLOCK_SYSTEM);
	 TimerLoadSet(TIMER0_BASE, TIMER_B, SysCtlClockGet());
	 IntEnable(INT_TIMER0B);
	 TimerIntEnable(TIMER0_BASE, TIMER_TIMB_TIMEOUT);
	 toggle = 0x00000000;
	 TimerEnable(TIMER0_BASE, TIMER_B);
    while(1)
    {

    }
}

1) In the above code i cant able to get the output

2) which I use the timer interrupt for TIMER A , the above code is working.   its not working in TIMER B
