W is high for read cycle.
Due to product sensitivities to noise, power supplies must be properly grounded and
decoupled, and bus contention conditions must be minimized or eliminated during read and
write cycles.
Addresses valid before or at the same time E goes low.
This parameter is sampled and not 100% tested.
Transition is measured ±200 mV from steady-state voltage.
