Notes:
1. All values are referenced to V_IL and/or V_IH.
2. Depending on the conversion command, the TH06 may hold the master during the conversion (clock stretch). At
above 100 kHz SCL, the TH06 may also hold the master briefly for user register and device ID transactions. At the
highest I²C speed of 400 kHz the stretching will be <10 µs.
3. Pulses up to and including 50 ns will be suppressed.
