(2)

To ensure the standard mode I2C frequency, fPCLK1 must be at least 2 MHz. To ensure the fast mode I2C

frequency, fPCLK1 must be at least 4 MHz. To ensure the fast mode plus I2C frequency, fPCLK1 must be at least a

multiple of 10 MHz.

(3)

The device should provide a data hold time of 300 ns at least in order to bridge the undefined region of the

falling edge of SCL.
