Bus Cycle Control via READY Input
The duration of an external bus cycle can be controlled by the external circuitry via the
READY input signal.
Synchronous READY permits the shortest possible bus cycle but requires the input
signal to be synchronous to the reference signal CLKOUT.
Asynchronous READY puts no timing constraints on the input signal but incurs one
waitstate minimum due to the additional synchronization stage.

depends on the MTTC waitstate of the current cycle, and on the MCTC waitstates
and the ALE mode of the next following cycle. If the current cycle uses a multiplexed
bus the intrinsic MUX waitstate adds another CLKOUT cycle to the READY
deactivation time.
