eSPI Interface Intel Atom Processor

Hi All,

Is there anyone know how to configure the Enhanced Serial Peripheral Interface (eSPI) in the Atom E3940 processor. I've searched for the eSPI info for weeks, but can't get what I'm looking for.

Below are the detail:
Processor: Intel Atom x5-E3940
OS: Windows 10 IoT Enterpreise
Language: C++
Compiler: VS 2019

I found out there is a Serial Peripheral Interface (SPI) Driver for Windows* Programmer’s Guide provided by Intel. I wonder is there any similar document for the eSPI in Atom E3940 processor?

Any help is much appreciated.

Thank You.

Regards,
SG
