Access:
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
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.
• WORDADDR
During a page read, this value contains the word address (8-bit or 16-bit word depending on the memory plane organiza-
tion) where an error occurred, if a single error was detected. If multiple errors were detected, this value is meaningless.
