Command Sequence for Read/Write Operations (except Status Register Read)
1. “r” designates bits reserved for larger densities.
2. It is recommended that “r” be a logical “0” for densities of 32M bits or smaller.
3. For densities larger than 32M bits, the “r” bit becomes the most significant Page Address bit for the appropriate density.
