Open-Drain Implementation + +**Decision**: Use GPIO input mode for '1' (high-impedance), output low for '0'. + +**Rationale**: +- True open-drain behavior requires external pull-ups +- Simulation can approximate by setting pin as input (high-impedance) +- Matches real hardware where SDA/SCL are never actively driven high + +### 3.
