请问为什么我的TM4C1294NCPDT上升沿计时器中断总是进入FaultISR(void)函数？

不知道为什么就是不对，看了一些帖子说加延时，然后我加了掩饰也是同样的效果。真的有点迷糊了

请参考下以下调试说明：

void Timer1AIntHandler(void)[unsigned long ulstatus;ulstatus = TimerIntStatus(TIMER1_BASE, TIMER_CAPA_EVENT);TimerIntClear(TIMER1_BASE, ulstatus);result=TimerValueGet(TIMER1_BASE, TIMER_A);if(result==0)[GPIOPinWrite(GPIO_PORTN_BASE, D2|D1, 3);]]void main(void)[ui32SysClkFreq=SysCtlClockFreqSet((SYSCTL_XTAL_25MHZ |SYSCTL_OSC_MAIN |SYSCTL_USE_PLL |SYSCTL_CFG_VCO_480), 120000000);SysCtlPeripheralEnable(SYSCTL_PERIPH_GPION);//Turn on LEDGPIOPinTypeGPIOOutput(GPIO_PORTN_BASE, D2|D1);SysCtlDelay(10);GPIOPinConfigure(GPIO_PD2_T1CCP0);GPIOPinTypeTimer(GPIO_PORTD_BASE,GPIO_PIN_2);GPIOPadConfigSet(GPIO_PORTD_BASE,GPIO_PIN_2, GPIO_STRENGTH_2MA, GPIO_PIN_TYPE_STD_WPU);TimerConfigure(TIMER1_BASE, TIMER_CFG_SPLIT_PAIR | TIMER_CFG_A_CAP_TIME_UP);TimerControlEvent(TIMER1_BASE, TIMER_A, TIMER_EVENT_POS_EDGE);TimerMatchSet(TIMER1_BASE, TIMER_A, 0x8FFF);TimerIntRegister(TIMER1_BASE, TIMER_A, Timer1AIntHandler);IntMasterEnable();TimerIntEnable(TIMER1_BASE, TIMER_CAPA_MATCH);IntEnable(INT_TIMER1A);TimerEnable(TIMER1_BASE, TIMER_A);while(1)[]]这两行操作的中断标志是不一样的吧。进入FaultISR(void)函数，首先怀疑是硬件配置的问题。
