Advanced Sector Protection Software Examples
Table 8.2
contains all possible combinations of the DYB, PPB, and PPB Lock Bit relating to the status of the
sector. In summary, if the PPB Lock Bit is locked (set to
0
), no changes to the PPBs are allowed. The PPB
Lock Bit can only be unlocked (reset to
1
) through a hardware reset or power cycle. See also
Figure 8.1
on page 44
for an overview of the
Advanced Sector Protection
feature.
