Once the entire main area of a page is written with data, this register content must be stored at any free location of the spare
area.
Parity calculated by the ECC-H.
During a page read, this field contains the word address (8-bit word) where an error occurred, if a single error was detected. If
multiple errors were detected, this field is meaningless.
During a page read, this field contains the corrupted bit offset where an error occurred, if a single error was detected. If multiple
errors were detected, this field is meaningless.
