19.11.5 Auto-Erase Mode
1. Auto-erase mode supports only entire memory erasing.
2. Do not perform a command write during auto-erasing.
3. Confirm normal end of auto-erasing by checking I/O6. Alternatively, status read mode can also
4. Status polling I/O6 and I/O7 pin information is retained until the next command write. As long
