程序始终无法进入中断，不知道为什么。。。求大神解答~~T^T
这是TIMER配置函数，
void InTimer_Init(void)
{
SysCtlPeripheralEnable(SYSCTL_PERIPH_WTIMER0);

SysCtlPeripheralEnable(SYSCTL_PERIPH_GPIOF);
SysCtlPeripheralEnable(SYSCTL_PERIPH_GPIOC);
//Ê¹ÄÜGPIOB ÍâÉè
GPIOPinTypeTimer(GPIO_PORTC_BASE, GPIO_PIN_4);
GPIOPinTypeGPIOInput(GPIO_PORTC_BASE, GPIO_PIN_4);
GPIOPinConfigure(GPIO_PC4_WT0CCP0);

// IntMasterEnable();//master interrupt enable API for all interrupts

TimerConfigure (InTimer_BASE,TIMER_CFG_A_CAP_COUNT_UP|TIMER_CFG_SPLIT_PAIR);//??????,?????
TimerControlEvent(InTimer_BASE,TIMER_A,TIMER_EVENT_POS_EDGE); TimerLoadSet (InTimer_BASE, TIMER_A,10);
TimerLoadSet (InTimer_BASE,TIMER_A,10000);
TimerMatchSet (InTimer_BASE,TIMER_A,1000);//
IntEnable(INT_TIMER0A);//Ê¹ÄÜ TIMER0A

TimerIntEnable(InTimer_BASE,TIMER_CAPA_EVENT);//¶¨Ê±Æ÷A ²¶»ñÊ±¼ä´¥·¢ÖÐ¶Ï
TimerEnable(InTimer_BASE, TIMER_A);//TIMER0A ¿ªÊ¼¼ÆÊý,¼ÆÊýÖµ = TimerLoadSet Ê±,´¥·¢ÖÐ¶Ï
}
