1.

2.

A device must internally provide an hold time of at least 300ns for the SDA signal (referred to VIHmin of the SCL signal) to

bridge the undefined region of the falling edge of SCL

3.

Cb = total capacitance of one bus line, in pF

4.

Measurement points are done at 0.2·Vdd_IO and 0.8·Vdd_IO, for both port
