Register Name:
Address:
Access Type:
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
• BITADDR9: corrupted bit address in the page between the 2304th and the 2559th 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.
• WORDADDR9: corrupted word address in the page between the 2304th and the 2559th 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
