TI中文支持网定时器中断和串口中断服务函数结束时没有继续运行主程序，但是中断服务函数依然可以正常进入，

按键中断正常返回主函数继续执行，目前测试了串口中断和定时器中断都不行
Susan Yang：
您把 Timer_A_clearInterruptFlag(TIMER_A1_BASE); 去掉试试
gaoyang9992006：
参考mspware里的例子，然后你的while里不要这么做先，先在中断里弄个变量，每次中断翻转这个变量，然后将这个变量在主函数查询是否变化，如果改变通过一个LED或者串口打印出来，这样才能确定到底执行没有执行返回。我觉得可能是你while循环里写的这个测试方式是有问题的。
