Whichnoart of the pico are you referring to specifically? Never heard the term "GPIO engine" before. Is that sort of like the USB stack but for GPIO?
I think they meant PIO (programmable IO). It’s like a small processor tied to some of the IO pins. There’s a very small set of instructions and some state machines.
It can be used to implement your own IO protocols without worrying about the issues that come with bit-banging from the cpu.
The GPIO engine is a simple state machine that can be programmed to implement high-speed data transfer, digital video output, and many other purposes. It is one of the best and most innovative features on the Pico.
