ESP32's internal layout and control

[SoftwareSamurai]

Is there a technical document of the internal control and communication of the ESP32 subsystems with the microprocessor(s)?
For example, how is data transferred between the microprocessor(s) and the radio? DMA? And how is the radio controlled? Special registers?
(Assuming this information isn't some trade secret or such.)

That's good, and thank you for that krzychb. It explains a lot. But there's no information regarding the control and usage of the radio subsystem (sans enabling the clock for it). Is there a second document for that?

The low level "information regarding the control and usage of the radio subsystem " is an intellectual property of Espressif and not published.

On higher level you operate it with an API of Wi-Fi Driver documented in https://esp-idf.readthedocs.io/en/lates ... _wifi.html and https://esp-idf.readthedocs.io/en/lates ... /wifi.html

That's what I thought. Okay, thanks.
