W is high for read cycle. Power supplies must be properly grounded and decoupled, and bus contention conditions must be
minimized or eliminated during read or 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 the steady-state voltage.
