Figure 8. Deferred Bus Mode Timing Diagram
Deferred Bus Timing Mode
Deferred Bus Cycle Mode: This bus mode (enabled by setting CCB1.5) reduces bus contention
when using the 80C196EA in demultiplexed mode with slow memories. As shown in
delay of 2t occurs in the first bus cycle following a chip-select output change and the first write
cycle following a read cycle.
