The CS signal should be in the high state before the RESET signal is deasserted.
1. “r” designates bits reserved for larger densities.
2. It is recommended that “r” be a logical “0”.
3. For densities larger than 1M bit, the “r” bits become the most significant Page Address bit for the appropriate density.
