Changing pin state: ISA Question

Hello, I'm new to uCs. I intend to buy some. I'm just not sure which type.

How does the ESP32s work?

Thanks

Also interesting is that you could, in theory, reverse engineer the docs from the gcc code to translate programs to LX6 assembly, but nobody appears to have done that yet...
