Chip Select Change Wait States
Figure 11-15. External Wait
Notes:
A chip select wait state is automatically inserted when consecutive accesses are made to two
different external memories (if no wait states have already been inserted). If any wait states
have already been inserted, (e.g., data float wait) then none are added.
