我现在想让gpio50口做为输入引脚做触发
1.先设置gpio为gpio模式
2.设置gpio方向为输入
3.设置取消上拉
为何我运行时候gpio50口的data直接就成了高电平？
我测量过，是低电平啊
单步执行的时候正常，连续运行时就data变高电平了
由于GPIO的data寄存器读修改写的原因，参照http://processors.wiki.ti.com/index.php?title=General_Purpose_IO_(GPIO)_FAQ_for_C2000&keyMatch=GPIO%20FAQ&tisearch=Search-CN-Everything#Q:_Back-to-back_DAT_register_writes_do_not_work_as_expected
