NOTES:
1. WE must be HIGH when there is a change in A0 - A10.
2. When CE and WE are both LOW at the same time, write occurs during the period tWP.
3. tWR is the time from the rise of CE or WE, whichever is first, to the end of the write cycle.
4. If CE LOW transition occurs at the same time or after WE LOW transition, the outputs will remain high-impedance.
5. DOUT outputs data with the same logic level as the input data of this write cycle.
6. If CE is LOW during this period, the input/output pin is in the output state. During this state, input
signals of opposite logic level must not be applied.
