NOTES:

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

2. Timing depends on which signal is de-asserted first, CE, OE, LB, or UB.

3. tBDD delay is required only in case where opposite port is completing a write operation to the same address location for simultaneous read operations

BUSY has no relation to valid output data.

4. Start of valid data depends on which timing becomes effective last tABE, tAOE, tACE, tAA or tBDD.

5. SEM = VIH.
