CC2640引脚配置

请问一下CC2640的可以配置成浮空输入或者是高阻态吗？我看参考的文档上没有

有啊，在 CC26xx Technical Reference Manual 第11.6节：

By default, the I/O driver (output) and input buffer (input) are disabled at power on or reset, and thus the I/O pin can safely be left unconnected (floating). If the I/O pin is tri-stated and connected to a node with a different voltage potential; there might be a small leakage current going through the pin. The same applies to an I/O pin configured as input, where the pin is connected to a voltage source (for example VDD / 2). The input is then an undefined value of either 0 or 1.

可是在下面的模式配置没看到耶。还是说只有复位和刚上电的时候才默认是浮空的，而不能自己配置
