Is there a web page that describes how the ESP32 core, executes code from a single serial FLASH chip ?
What does the timing look like during execution ?
How is a single FLASH chip shared between the two ESP32 cores ?

I have seen diagrams with a serial FLASH and a serial RAM connected to the same pins on the ESP32 core.
What does the timing look like for this setup ?

Thank You
