P1_0引脚用于软件模拟IIC 数据线SDA时会出现在等待从机应答的时候SDA脚会出现几十纳秒的高电平 非应用程序造成，如果将引脚改为P0_7脚就不会出现这个情况请问时什么原因呢？
P1_0脚是有什么特殊的地方吗？希望得到你们专业的解答。另外我看到以前有人提过相类似的问题主要是在P1_0 和P1_1引脚上模拟IIC时序出现了问题。这个问题最终是怎么解决的呢？他们的问题在论坛上提出的时间已经很久了一个是五年前一个是八年前。下面是相关链接依然没有找到明确的答案。 最后还有我在程序中看到有这样一段代码P1_0 = !P1_0; //add by 1305106 不知道这个引脚本身是不是在协议栈封装的程序中已经就另作他用？

经过仔细调试程序之后发现是程序中设置SDA的输入 输出时出现的bug 已经得到解决。不用理会该问题。
