Measure each of these states on real hardware before writing a value.

- Do not classify pins whose state users can change through buttons, connectors,

- Use `up` / `down` / `floating` for pins defined by resistors alone.
- Use `fixed` for a driven pin only when the driver is always powered. For example,
an EPD BUSY output reads D normally and U while the EPD is in deep sleep, so it can
