NOTES:
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 LOW CE and a LOW R/ W for memory array writing cycle.
3. t WR is measured from the earlier of CE or R/ W (or SEM or R/ W ) going HIGH 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 or SEM LOW transition occurs simultaneously with or after the R/ W LOW transition, the outputs remain in the High-impedance state.
6. Timing depends on which enable signal is asserted last, CE , or R/ W .
7. Timing depends on which enable signal is de-asserted first, CE , or R/ W .
8. If OE is LOW during 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 and data to be placed on the
bus for the required t DW . If OE is HIGH 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 .
9. To access RAM, CE = V IL and SEM = V IH . To access Semaphore, CE = V IH and SEM = V IL . t EW must be met for either condition.
