Notes:
1. All values are referenced to V_IL and/or V_IH.
2. Depending on the conversion command, the Si7013 may hold the master during the conversion (clock stretch). At
above 300 kHz SCL, the Si7013 may hold the master briefly for user register and device ID transactions. At the highest
I²C speed of 400 kHz the stretching will be <50 μs.
3. Pulses up to and including 50 ns will be suppressed.
