Output numbers depend on the value programmed into the IFDR; an IFDR programmed with the
maximum frequency (IFDR = 0x20) results in minimum output timings as shown in Table 24. The
I2C interface is designed to scale the actual data transition time to move it to the middle of the
I2C_SCL low period. The actual position is affected by the prescale and division values
programmed into the IFDR; however, the numbers given in Table 24 are minimum values.

Because I2C_SCL and I2C_SDA are open-collector-type outputs, which the processor can only
actively drive low, the time I2C_SCL or I2C_SDA take to reach a high level depends on external
signal capacitance and pull-up resistor values.
