There is no access to the file system nor to the manipulation of the S0ix states. The power management of the board is on the Atom-side
Take a look at the "Waking up the host CPU using the MCU" example, it will give you an idea on how to proceed in order to achieve what you have in mind.
thank you for the reply; I just want to lower the MCU's power consumption and since the S0ix state was mentioned in the Intel webpage I thought it could be configured.
Do you know if the mcu_sleep lowers the frequency while "sleeping"?
The mcu_sleep function pauses the application for a period of time the "Waking up the host CPU using the MCU" application allows to wake up the host with host_send function.
You can find more information about the functions in: C:\MCU\docs\api_doc\html\mcu__api_8h.html [Where MCU is the folder you used for the installation]
