PDL127H/129H SecSi Sector Protection Algorithm
■
To verify the protect/unprotect status of the SecSi
Sector, follow the algorithm shown in Figure 4.
Once the SecSi Sector is locked and verified, the sys-
tem must write the Exit SecSi Sector Region com-
mand sequence to return to reading and writing the
remainder of the array.
The SecSi Sector lock must be used with caution
since, once locked, there is no procedure available for
unlocking the SecSi Sector area and none of the bits
in the SecSi Sector memory space can be modified in
any way.
SecSi Sector Protection Bits
The SecSi Sector Protection Bits prevent program-
ming of the SecSi Sector memory area. Once set, the
