Notes
Document Number: 38-06054 Rev. *D
42. ADS = V
43. Addresses do not have to be accessed sequentially since ADS = V
44. Timing shown is for x18 bus matching; x9 bus matching is similar with 4 cycles between address inputs.
45. See table “Right Port Operation“ for data output on first and subsequent cycles.
46. CE = ADS = CNTEN = V
47. During “No Operation,” data in memory at the selected address may be corrupted and should be rewritten to ensure data integrity.
48. Output state (HIGH, LOW, or High-Impedance) is determined by the previous cycle control signals.
