PCLK1
must be at least 2 MHz to achieve standard mode I2C frequencies. It must be at least
4MHz to achieve fast mode I2C frequencies, and a multiple of 10 MHz to reach the 400 kHz
maximum I2C fast mode clock.
3. The maximum hold time of the Start condition has only to be met if the interface does not
stretch the low period of SCL signal.
4. The device must internally provide a hold time of at least 300ns for the SDA signal in order to
bridge the undefined region of the falling edge of SCL.
