Research direction

Start with api/Common.h at the linked PinMode enum and review how these pin modes are represented in the ArduinoCore-API. Check related API declarations or tests, if present, before confirming the requested open-drain and push-pull modes and their naming; done means the API exposes the agreed modes consistently.
