A timing diagram of the external multiplexed-bus is illustrated in Figure 18-25 with the actual timing
values shown on table Table A-32. All major bus signals are included in the diagram. Although both a data
write and data read cycle are shown, only one or the other would occur on a particular bus cycle.
The expanded bus timings are highly dependent on the load conditions. The timing parameters shown
assume a balanced load across all outputs.
