Depending on the system's load conditions, the RD signal may lag behind the CS signal. An
example is shown in figure 8.42. In this case, with the setting for no idle cycle insertion (a), there
may be a period of overlap between the RD signal in bus cycle A and the CS signal in bus cycle B.
Setting idle cycle insertion, as in (b), however, will prevent any overlap between the RD and CS
signals. In the initial state after reset release, idle cycle indicated in (b) is set.
