Once the entire main area of a page is written with data, the register content must be stored at any free location of the
spare area.
• BITADDR3: corrupted Bit Address in the page between the1536th and the 2047th bytes
During a page read, this value contains the corrupted bit offset where an error occurred, if a single error was detected. If
multiple errors were detected, this value is meaningless.
• WORDADDR3 corrupted Word Address in the page between the 1536th and the 2047th bytes
During a page read, this value contains the word address (8-bit word) where an error occurred, if a single error was
detected. If multiple errors were detected, this value is meaningless.
