NOTES:

1. A write occurs during the overlap of E low and W low.

2. E1 and E2 are represented by E in this data sheet. E2 is of opposite polarity to E.

3. All timings are referenced from the last valid address to the first transitioning address.

4. If E goes low coincident with or after W goes low, the output will remain in a high impedance state.

5. If E goes high coincident with or before W goes high, the output will remain in a high impedance state.
