1. Parameters are valid over specified temperature and voltage range.
2. All voltage measurements are referenced to ground (GND). For testing, all inputs swing between 0 V and 3.0 V with a transition time of 5 ns
3. Test conditions for outputs: C
4. Resetting the device while actively communicating on the bus may cause glitches or an errant STOP condition.
5. Upon reset, the full delay will be the sum of t
