ECC Status ASO
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.
The ECC Status ASO displays the status of any error correction action taken when reading a Page of the
main flash array. A single word of status is displayed at word location 0 of each Page.
