TMS320C32 Enhanced External Memory Interface

Figure 10–25 shows a one wait-state read sequence and Figure 10–26 shows
the write sequence for STRBx active. On the first H1 cycle, RDY is high; therefore,
the read or write sequence is extended for one extra cycle. On the second H1
cycle, RDY is low and the read or write sequence is terminated.
