将此引脚连接到GND,然后在配置过程中所有GPIO将通过内部上拉电阻上拉。
该引脚为高电平将所有GPIO置于3态。

Connect this pin to GND and then all the GPIOs during configuration process will be pulled up through internal pull-up resistors. This pin being High places all the GPIOs in 3-state.------------------------------------------------------------------------------------------------------------
