All values are referenced to VIL and/or VIH. 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. 1/fSCL tSKH tSP tSKL SCL tBUF tSTH tDS tDH tSPS SDA D7 D6 D5 D0 R/W ACK Start Bit Stop Bit tSTS tVD : ACK Figure 1. I2C Interface Timing Diagram |
