Dynamic Protection Bits (DYB) ASO
The DYB ASO contains one bit of a volatile memory array for each Sector in the device. When the DYB ASO
is entered, the DYB bit for a sector appears in the Least Significant Bit (LSB) of each word in the sector.
Reading any word in a sector displays a word where the LSB indicates the non-volatile protection status for
that sector. However, it is recommended to read, set, or clear the DYB only at word location 0 of the sector for
future compatibility. If the bit is 0 the sector is protected against programming and erase operations. If the bit
is 1 the sector is not protected by the DYB. The sector may be protected by other features of ASP.
