Output timings refer to the rising edge of CLKOUT.
Input timings are calculated from the time, when the input signal reaches
VIH or VIL, respectively.

For timing purposes a port pin is no longer floating when a 100 mV
change from load voltage occurs, but begins to float when a 100 mV
change from the loaded VOH /VOL level occurs (IOH / IOL = 20 mA).
