A device model in the simulation engine, reached through a dedicated dispatch path rather than the peripheral registry.
The 4x4 R1-R4/C1-C4 matrix compiles to a real keypad device: it reads the four row output pins and drives the four column input pins so a firmware row-drive/column-read scan detects the pressed key (host-set via the standard "key" stimulus). Reached through from_config, not a kit, so it is absent from the generated manifest.
Simulated device model
Built from the datasheet. Implemented from the part’s register documentation and exercised by automated tests. Nothing physical was ever placed next to it.
