Cycle as programmed, including MCTC waitstates (Example shows 0 MCTC WS).
The leading edge of the respective command depends on RW-delay.
READY (or READY) sampled HIGH (resp. LOW) at this sampling point generates a
READY controlled waitstate, READY (resp. READY) sampled LOW (resp. HIGH) at this
sampling point terminates the currently running bus cycle.
READY (resp. READY) may be deactivated in response to the trailing (rising) edge of the
corresponding command (RD or WR).
If the Asynchronous READY (or READY) signal does not fulfill the indicated setup and
hold times with respect to CLKOUT (e.g. because CLKOUT is not enabled), it must fulfill t
37 in order to be safely synchronized. This is guaranteed, if READY is removed in
response to the command (see Note 4)).
