RD) Signal
Depending on the system’s load conditions, the
RD signal may lag behind the CS signal. An
example is shown in figure 6.33.
In this case, with the setting for no idle cycle insertion (a), there may be a period of overlap
between the bus cycle A
RD signal and the bus cycle B CS signal.
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 insertion (b) is set.
