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 29
. The I

C
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 29
are minimum values.

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