Figure 20:

I2C Interface Timing

(1)

I2C interface timing is based on a 400 kHz mode.

(2)

The beginning of a rising edge and the end of a falling edge are at 10% of the amplitude of the signal. The end of a

rising edge and the beginning of a falling edge are at 90% of the amplitude of the signal.
