Notes :
1. WE or CE must be HIGH during all address transitions.
2. A write occurs during the overlap of a low CE , and a low WE .
3. During a WE controlled with write cycle with OE LOW, tWP must be greater than tWHZ+tDW to allow the I/O drivers to turn
off and data to be placed on the bus.
4. During this period, I/O pins are in the output state, and input signals must not be applied.
5. If the CE LOW transition occurs simultaneously with or after WE LOW transition, the outputs remain in a high Impedance
state.
6. tOW and tWHZ are specified with CL=5pF. Transition is measured ±500mV from steady state.
