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 cases where the 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 tAOE, tACE, tAA or tBDD.

5. SEM = VIH.
