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 D6. Alternatively, status read mode can also
4. Status polling D6 and D7 pin information is retained until the next command write. As long as
I/O5–I/O0
A16–A0
be used for this purpose (D7 status polling uses the auto-erase operation end identification
pin).
the next command write has not been performed, reading is possible by enabling CE and OE.
