Figure 4-3 Example Circuit to Control Supply Sequencing
4.4 AC Electrical Characteristics
Timing waveforms in
Section 4.2
are tested with a V
IL
maximum of 0.8 V and a V
IH
minimum of 2.0 V
for all pins except XTAL, which is tested using the input levels in
Section 4.2
.
In
Figure 4-4
the levels of
V
IH
and V
IL
for an input signal are shown.
Figure 4-4 Input Signal Measurement References
Figure 4-5
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 V
OL
or V
OH.
Data Invalid state, when a signal level is in transition between V
OL
and V
OH.
