Figure 10-2 Input Signal Measurement References
Figure 10-3 shows the definitions of the following signal states:
Active state, when a bus or signal is driven, and enters a low impedance state
Tri-stated, when a bus or signal is placed in a high impedance state
Data Valid state, when a signal level has reached VOL or VOH
Data Invalid state, when a signal level is in transition between VOL and VOH
