AC CHARACTERISTICS
Notes:
1. Figure shows total number of clock cycles set to four.
2. Figure shows that PS (power saving mode) has been enabled; one additional wait state occurs during initial data Da. Latency
is not present if PS is not enabled.
3. If any burst address occurs at a 64-word boundary, two additional clock cycle are inserted, and are indicated by RDY.
