1. W is high for read cycle.
2. Product sensitivites to noise require proper grounding and decoupling of power supplies during read and write cycles.
3. All read cycle timings are referenced from the last valid address to the first transitioning address.
4. This parameter is sampled and not 100% tested.
5. Device is continuously selected (S
6. Addresses valid prior to or coincident with S going low.
