Intel GPIO
![userHead](/forum/images/userhead.png)
Is there any new documentation regarding the Intel GPIO (U1 pinout) and how to use it?
The U1 pinout shown on the Input and Output documentation seems incomplete. Pin 1 and Pin 3 are both shown as "IC2_2 SCL". I'd expect one of them to be "IC2_2 SDA", similar to how there is both "IC2_0 SCL" and "IC2_0 SDA".
Is "DDIO SDA" and "DDIO SCL" for pins 5 and 7 correct? What does "DDIO" stand for? When searching all I can find is "Intel Data-Direct IO" which does not seem to be accessible from software. How does one access them?
I'm most interested in pins 5 and 7 having better documentation. Better description of their names and what they are wired to on the Intel X-Z8300 core.
