Standard mode I2C(1)
1.
Guaranteed by design, not tested in production.
Fast mode I2C(1)(2)
2.
fPCLK1 must be higher than 2 MHz to achieve standard mode I
2C frequencies. It must be higher than
4 MHz to achieve fast mode I2C frequencies. It must be a multiple of 10 MHz to reach the 400 kHz
maximum I2C fast mode clock.

The maximum hold time of the Start condition only has to be met if the interface does not stretch the low
period of SCL signal.

The device must internally provide a hold time of at least 300 ns for the SDA signal in order to bridge the
undefined region of the falling edge of SCL.
