Description
Disables error correction of decoded data.
Enables error correction of decoded data. Significant only
if hamming code operation is disabled (0x60[7]).
Description
Majority voting logic (MVL) based error correction.
Sigma deviation based error correction.
Corrects weak bit identified by both modes. If no common
bit is identified, bit identified by Sigma deviation methods
is corrected.
Corrects weak bit identified by both modes. If no common
bit is identified, bit identified by MVL method is
corrected.
