Byte/Buffer Address
(BA9-BA0/BFA9-BFA0)
Notes: 1. “r” designates bits reserved for larger densities.
2. It is recommended that “r” be a logical “0” for densities of 16M bits or smaller.
3. For densities larger than 16M bits, the “r” bits become the most significant Page Address bit for the appropriate density.
