When software wait insertion is specified by WCR2, the external wait input RDY signal is also
sampled. RDY signal sampling is shown in figure 10.11. A single-wait cycle as a software wait is
specified in figure 10.11. Sampling is performed at the transition from the Tw state to the T2 state;
therefore, the RDY signal has no effect if asserted in the T1 cycle or in the first Tw cycle. The
RDY signal is sampled on the rising edge of the clock.
