NOTES:
1. A write occurs during the overlap of E low and W low.
2. For common I/O applications, minimization or elimination of bus contention conditions is necessary during read and write cycles.
3. All write cycle 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 condition.
5. If E goes high coincident with or before W goes high, the output will remain in a high impedance condition.
