Webb16 juni 2024 · "tHD:DAT", or data hold time, for I2C is defined from the low-threshold end of the falling edge of SCL (VIL = 30% of VDD), to the start of the falling or rising edge of SDA (70% or 30% of VDD). From the screenshot, it does seem like this time is > 300 ns and on the 600 ns range. It looks ok to me.

WebbIf the data line (SDA) is stuck LOW, the master should send nine clock pulses. The device that held the bus LOW should release it sometime within those nine clocks. If not, then use the HW reset or cycle power to clear the bus. The master I2C must be able to generate this “bus clear” sequence.
