Fig.7 Waveforms showing the clock input (CP) to
TC propagation delays, the clock pulse width,
the output transition times and the maximum
clock pulse frequency.
Fig.8 Waveforms showing the TE to TC
propagation delays.

Fig.9 Waveforms showing PL, MR, Pn to TC
propagation delays.
Fig.10 Waveforms showing removal time for
MR and PL.
The shaded areas indicate when the input is permitted to change
for predictable output performance.
