1 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 22. The I2C interface is
designed to scale the actual data transition time to move it to the middle of the SCL low period. The actual
position is affected by the prescale and division values programmed into the IFDR; however, the numbers
given in Table 22 are minimum values.

2 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.
