Advanced Sector Protection/Unprotection
The Advanced Sector Protection/Unprotection feature disables or enables programming or erase operations
in any or all sectors and can be implemented through software and/or hardware methods, which are
independent of each other. This section describes the various methods of protecting data stored in the
memory array. An overview of these methods in shown in
Figure 8.1 on page 44
.

Notes:
1. Bit is volatile, and defaults to 1 on reset.
2. Programming to 0 locks all PPBs to their current state.
3. Once programmed to 0, requires hardware reset to unlock.
4. N = Highest Address Sector.
5. 0 = Sector Protected,
1 = Sector Unprotected.
6. PPBs programmed individually, but cleared collectively.
7. 0 = Sector Protected,
1 = Sector Unprotected.
8. Protect effective only if PPB Lock Bit is unlocked and
corresponding PPB is 1 (unprotected).
9. Volatile Bits: defaults to user choice upon power-up
(see ordering options).
