Notes:
1. Pre-writing (all erase block data are cleared to 0) is not necessary.
2. Verify data is read out in 16 bit size (word access).
3. Erasing block register (EBR) can be set about 1 bit at a time.
4. Erasing is performed block by block. When multiple blocks must be erased,
5. This is a recommended value. To change it, consult tables 27.12, 27.25, 27.37, 27.49, and 27.59 and select
