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.
• BITADDR: Corrupted Bit Address in the page between (i x 256) and ((i + 1) x 512) - 1) Bytes
• During a page read, this value contains the corrupted bit offset where an error occurred, if a single error was
• WORDADDR: Corrupted Word Address in the page between (i x 256) and ((i + 1) x 512) - 1) 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.
• NPARITY: Parity N
