WP76xx GPIO default state


Can anybody tell me definitively the default state of GPIO lines at power-up? The WP76xx Tech Spec simply says “No pull”, so can I safely assume that the pin state is an input?

The reason for asking is I’ll be using some GPIO to provide a couple of switched outputs and I want to ensure that they are OFF during power up and boot.


You can read it in /sys/class/gpio

That doesn’t really help. I’m talking about the actual state of the chip hardware BEFORE the kernel or any drivers start to load.
