There's exactly 0 overhead and the state machines run a custom assembly language with simplified instructions. In this example implementation of a [ring oscillator](https://pub.pages.cba.mit.edu/ring/), pin 1 is configured as a PIO input, and pin 2 as an output. Reading, inverting and writing is as simple as:
