NOTES:

1. Timing depends on which signal is asserted last, OE or CE.

2. Timing depends on which signal is deasserted first, OE or CE.

3. tBDD 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, tAOE, tACE, tAA, or tBDD.

5. R/W = VIH, and the address is valid prior to or coincidental with CE transition LOW.
