Notes:
1. Address format A14-A0 (Hex), Addresses A19-A15 can be VIL or VIH, but no other value, for the Command
sequence.
2. DQ7-DQ0 can be VIL or VIH, but no other value, for the Command sequence.
3. WA = Program byte address.
4. SAX for Sector-Erase; uses A19-A12 address lines.
BAX for Block-Erase; uses A18-A16 address lines.
5. The device does not remain in Software Product ID mode if powered down.
6. Both Software ID Exit operations are equivalent.
7. Refer to Figure 9 for more information.
