I²C interface - timing characteristics

Timing characteristics are shown in Table 6. I2C interface - timing characteristics for fast mode plus (1 MHz)

and Table 7. I2C interface - timing characteristics for fast mode (400 kHz). Refer to Figure 16. I2C timing

characteristics for an explanation of the parameters used.

Timings are given for all process, voltage, and temperature (PVT) conditions.
