BUS CYCLE WAVEFORMS

Figures 18 through 24 present the various bus cy-

cles that are generated by the processor What is

shown in the figure is the relationship of the various

bus signals to CLKOUT These figures along with

the information present in AC Specifications allow

the user to determine all the critical timing analysis

needed for a given application
