NOTES:
1. Timing depends on which signal is aserted last, OE or CE .
2. Timing depends on which signal is deaserted first, OE or CE .
3. t BDD delay is required only in a 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.
4. Start of valid data depends on which timing becomes effective last, t AOE, t ACE, t AA, or t BDD.
5. R/ W = V IH , CE = V IL , and OE = V IL , and the address is valid prior to other coincidental with CE transition LOW.
