NOTES(WRITE CYCLE)
1. WE is high for read cycle.
2. All read cycle timing is referenced from the last valid address to the first transition address.
3. t
4. At any given temperature and voltage condition, t
5. Transition is measured 200mV from steady state voltage with Load(B). This parameter is sampled and not 100% tested.
6. Device is continuously selected with CS=V
7. Address valid prior to coincident with CS transition low.
8. For common I/O applications, minimization or elimination of bus contention conditions is necessary during read and write cycle.
