Reset Timing (Inactive Clock Polarity Low Shown)
Note:
The CS signal should be in the high state before the RESET signal is deasserted.
Command Sequence for Read/Write Operations (except Status Register Read)
Notes:
1. “r” designates bits reserved for larger densities.
2. It is recommended that “r” be a logical “0” for densities of 4M bits or smaller.
3. For densities larger than 4M bits, the “r” bits become the most significant Page Address bit for the appropriate density.
