Once the entire main area of a page is written with data, this register content must be stored to any free location of the spare
area.
Only PR2 to PR7 registers are available in this case.
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.
