NOTES:
1. R/ W = V IH, CE = V IL, and is OE = V IL. Address is valid prior to the coincidental with CE transition LOW.
2. t BDD delay is required only in the case where the opposite port is completing a write operation to the same address location. For simultaneous read operations, BUSY has
no relationship to valid output data.
3. Start of valid data depends on which timing becomes effective last t AOE , t ACE , t AA , and t BDD .
4. Timing depends on which signal is asserted last, OE or CE .
5. Timing depends on which signal is de-asserted first, OE or CE .
