NOTES:

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

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

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

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