Notes: 1. Preprogramming (setting erase block data to all 0) is not necessary.
2. Verify data is read in 16-bit (W) units.
3. Set only one bit in EBR1or EBR2. More than one bit cannot be set.
4. Erasing is performed in block units. To erase a number of blocks, the individual blocks must be erased sequentially.
5. See
