以下示例以周期模式配置TimerA0，并使用重复计数功能每隔2秒切换一次GPIO。注意：重复计数功能特定于TimerA0实例，而不是其他TimerA实例。这里是一次500毫秒，重复了四次
主函数：
#include "ti_msp_dl_config.h"int main(void)
{SYSCFG_DL_init();NVIC_EnableIRQ(TIMER_0_INST_INT_IRQN); //允许中断DL_SYSCTL_enableSleepOnExit(); //低功耗语句可以删掉DL_TimerA_startCounter(TIMER_0_INST); //让TIMA0开始计数while (1) {__WFI(); //低功耗语句可以删掉}
}void TIMER_0_INST_IRQHandler(void)
{switch (DL_TimerA_getPendingInterrupt(TIMER_0_INST)) //判断是不是TIMA0中断，并确定是TIMA0中哪一个中断{case DL_TIMERA_IIDX_REPEAT_COUNT: //如果是重复计数中断DL_GPIO_togglePins(GPIO_LEDS_PORT,GPIO_LEDS_USER_LED_1_PIN | GPIO_LEDS_USER_TEST_PIN);break;default:break;}
}

主函数中有这一函数：
DL_TimerA_getPendingInterrupt(TIMER_0_INST)
是用来判断终端是否来自TIMA0中断，并确定是TIMA0中的哪个中断
这里虽然名字有TIMERA，其实还是TIMER，这里有了重定义
