ASYNCHRONOUS TRUTH TABLE
Notes:
1. X means "Don't Care".
2. For write cycles following read cycles, the output buffers must be disabled with OE, otherwise data
3. Sleep Mode means power Sleep Mode where stand-by current does not depend on cycle time.
4. Deselected means power Sleep Mode where stand-by current depends on cycle time.
