TI中文支持网Part Number: MSP432P401R
我自己写的输入捕获要么乱进中断，要末进不去中断，要末计数错吴
Susan Yang：
请问能否详细说明一下？另外建议您先参考例程
https://www.ti2k.com/wp-content/uploads/ti2k/DeyiSupport_OtherMCU_node
Capture a number of periods of the VLO clock and store them in an array.

我就时参考例程写的

那能否说一下您想要具体实现什么功能？您现在使用的是开发板还是自制板？
另外请您以“插入–>代码”的形式上传代码，以便于阅读

先清除cov位，再把main里面的MAP_Interrupt_enableSleepOnIsrExit();删掉
