Figure 24 READY Timing
Note: If the READY input is sampled inactive at the indicated sampling point (âNot Rdyâ)
a READY-controlled waitstate is inserted (tpRDY),
sampling the READY input active at the indicated sampling point (âReadyâ)
terminates the currently running bus cycle.
Note the different sampling points for synchronous and asynchronous READY.
This example uses one mandatory waitstate (see tpE) before the READY input
value is used.
