Whether this delay occurs depends on the starting address.
The delay takes place only once, and only if the burst sequence crosses a 16-word
boundary. The WAIT pin informs the system of this delay. For timing diagrams of WAIT
functionality, see these figures:
• If the starting address is aligned to a 4-word boundary, there is no delay.
• If the starting address is the end of a 4-word boundary, the output delay is one
