Dynamic Protection Bits
Dynamic Protection Bits are volatile and unique for each sector and can be individually modified. DYBs only
control the protection scheme for unprotected sectors that have their PPBs cleared (erased to
1
). By issuing
the DYB Set or Clear command sequences, the DYBs are set (programmed to
0
) or cleared (erased to
1
),
thus placing each sector in the protected or unprotected state respectively. This feature allows software to
easily protect sectors against inadvertent changes yet does not prevent the easy removal of protection when
changes are needed.
