Table 3. Autoselect Codes (High Voltage Method)
Legend: L = Logic Low = VIL, H = Logic High = VIH, BA = Bank Address, SA = Sector Address, X = Don’t care.
Notes:
1. The autoselect codes may also be accessed in-system via command sequences.
2. PPB Protection Status is shown on the data bus
Sector/Sector Block Protection and Unprotection
The hardware sector protection feature disables both programming and erase operations in any
sector. The hardware sector unprotection feature re-enables both program and erase operations
in previously protected sectors. Sector protection/unprotection can be implemented via two
