NOTES:
1. Use Reset-Write-Protect flowchart. Enable Write/Erase operation to all blocks.
2. Use Block-Erase flowchart. Erasing a block clears any previously established lockout for that block.
3. Use Set-Write-Protect flowchart. This step re-implements protection to locked blocks.
4. Use Word/Byte-Write or 2-Byte-Write flowchart sequences to write data.
5. Use Block-Lock flowchart to write lock bit if desired.
