Notes
Document Number: 38-06054 Rev. *D
64. Output state (HIGH, LOW, or High-Impedance) is determined by the previous cycle control signals.
65. During “No Operation,” data in memory at the selected address may be corrupted and should be rewritten to ensure data integrity.
66. CE = B0 = B1 = B2 = B3 = V
67. No dead cycle exists during counter reset. A READ or WRITE cycle may be coincidental with the counter reset.
68. Output state (HIGH, LOW, or High-Impedance) is determined by the previous cycle control signals. Ideally, DATA
