1. Guaranteed by design, not tested in production.

2.

fPCLK1 must

achieve fast

be at least 2 MHz to achieve

mode I2C frequencies, and a

standard mode I2C frequencies. It must

multiple of 10 MHz to reach the 400 kHz

be at least 4 MHz

maximum I2C fast

to

mode

clock.

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

signal.
