Notes:
29. R/W must be HIGH during all address transitions.
30. A write occurs during the overlap (tSCE or tPWE) of a LOW CE or SEM.
31. tHA is measured from the earlier of CE or R/W or (SEM or R/W) going HIGH at the end of write cycle.
32. If OE is LOW during a R/W controlled write cycle, the write pulse width must be the larger of tPWE or (tHZWE + tSD) to allow the I/O drivers to turn off and
data to be placed on the bus for the required tSD. 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 tPWE.
33. Transition is measured
±500 mV from steady state with a 5-pF load (including scope and jig). This parameter is sampled and not 100% tested.
34. To access RAM, CE = VIL, SEM = VIH.
35. During this period, the I/O pins are in the output state, and input signals must not be applied.
36. 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.
