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

I2C_SCL low period. The actual position is affected by the prescale and division values
programmed into the IFDR; however, the numbers given in
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.
Specified at a nominal 50-pF load.
