NOTES:
1
Programming IFDR with the maximum frequency (IFDR=0x20) results in the minimum output timings listed. The
I2C interface is designed to scale the data transition time, moving it to the middle of the SCL low period. The actual
position is affected by the prescale and division values programmed in IFDR.

Because SCL and SDA are open-drain-type outputs, which the processor can only actively drive low, the time SCL
or SDA takes to reach a high level depends on external signal capacitance and pull-up resistor values
