I want to read/write the high/low of GPIO pins of Intel Atom c3930 in Windows enterprise. I have found some information about GPIO . But I don't have any document about GPIO access, including how to set control registers and where to the high/low of pins.

Hello, @Huuuyen:

Thank you for contacting Intel Embedded Community.

The cited part number is not an Intel valid part number. You can confirm this information in the following website:

https://ark.intel.com/

In case that you refer to the Intel Atom® x5-E3930 Processor, you can find the information that may help you in section 19, on pages 190 through 202 of the Apollo Lake Platform Intel Architecture Firmware Specification (Volume 2 of 2) BIOS Specification document # 559811. It  can be found when you are logged into your Resource & Design Center (RDC) privileged account on the following website:
