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.
