Document Number: 38-06054 Rev. *E
21. In this depth expansion example, B1 represents Bank #1 and B2 is Bank #2; Each Bank consists of one Cypress dual-port device from this data sheet.
22. B0 = B1 = B2 = B3 = BM = SIZE = ADS = CNTEN = V
23. The same waveforms apply for a right port write to flow-through left port read.
24. CE = B0 = B1 = B2 = B3 = ADS = CNTEN=V
