Dears:
I want to use GPIO10 of TUSB9261 to check if this chip has any Data input or output.
If there is no input or output ,I want to let GPIO10 output a low voltage signal to help me cotrol the power of the sata disk.
But I don't know how to customer firmware to set GPIO 10 fucntion ,it 's always a high voltage output.
我想用TUSB9261的GPIO10端口来实现这样一个功能：
如果TUSB9261无任何输入输出，则给GPIO10一个低电平输出，用它来控制我硬盘电源的关断，但现在不知如何更改GPIO10的配置，他一直是高电平输出。
