Notes :  
1.WE#, CE# must be high or CE2 must be low during all address transitions.  
2.A write occurs during the overlap of a low CE#, high CE2, low WE#.  
3.During a WE#controlled write cycle with OE# low, tWP must be greater than tWHZ + tDW to allow the 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 and CE2 high 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.
