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