BUS CYCLE WAVEFORMS
Figures 16 through 24 present various bus cycles that are generated by the processor. What is shown in the
figure is the relationship of the various bus signals to CLK2. These figures along with the information present in
AC Specifications allow the user to determine critical timing analysis for a given application.
