WAIT State P33 130nm

After encountering an EOWL situation, periodic WAIT states can occur in general as

illustrated in Figure 4, “Periodic WAIT State Timing Diagram” on page 15.

Figure 10, “Periodic Data and WAIT State Comparison” on page 15 shows that P33

130nm has periodic WAIT states, but P33 65nm does not.
