Demultiplexed Bus Cycle
4.7.5.1
Bus Cycle Control with the READY Input
The duration of an external bus cycle can be controlled by the external circuit using the
READY input signal. The polarity of this input signal can be selected.
Synchronous READY permits the shortest possible bus cycle but requires the input
signal to be synchronous to the reference signal CLKOUT.
An asynchronous READY signal puts no timing constraints on the input signal but incurs
a minimum of one waitstate due to the additional synchronization stage. The minimum
