NOTES:
1
A write occurs during the overlap of E low and W low.
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.
If G goes low at the same time or after W goes low, the output will remain in a high-impedance state.
After W, E, or UB/LB has been brought high, the signal must remain in steady-state high for a minimum
of 2 ns.
If both byte control signals are asserted, the two signals must have no more than 2 ns skew between
them.
The minimum time between E being asserted low in one cycle to E being asserted low in a subsequent
cycle is the same as the minimum cycle time allowed for the device.
All write cycle timings are referenced from the last valid address to the first transition address.
