1. Write cycle parameters should be adhered to, in order to ensure proper writing.
2. CE L = CE R = V IL. OE "B" = V IL.
3. Port "A" may be either left or right port. Port "B" is the opposite from port "A".

1. R/ W or CE must be HIGH during all address transitions.
2. A write occurs during the overlap (t EW or t WP ) of a CE =V IL and R/ W = V IL .
3. t WR is measured from the earlier of CE or R/ W going to V IH to the end-of-write cycle.
4. During this period, the I/O pins are in the output state, and input signals must not be applied.
5. If the CE = V IL transition occurs simultaneously with or after the R/ W = V IL transition, the outputs remain in the High-impedance state.
6. Timing depends on which enable signal ( CE or R/ W ) is asserted last.
7. This parameter is guaranteed by device characterization, but is not production tested. Transition is measured 0mV from steady state with the Output Test Load
(Figure 2).
8. If OE = V IL during a R/ W controlled write cycle, the write pulse width must be the larger of t WP or (t WZ + t DW ) to allow the I/O drivers to turn off data to be placed on the bus
for the required t DW . If OE = V IH during an R /W controlled write cycle, this requirement does not apply and the write pulse can be as short as the specified t WP .
