36. t
37. If OE is LOW during a R/W controlled write cycle, the write pulse width must be the larger of t
38. To access RAM, CE = V
39. To access upper byte, CE = V
40. Transition is measured 500 mV from steady state with a 5 pF load (including scope and jig). This parameter is sampled and not 100 percent tested.
41. During this period, the IO pins are in the output state, and input signals must not be applied.
42. 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.
