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.
• NPARITY1: Parity N
Parity alculated by the ECC-H.
• WORDADDR1: corrupted Word Address in the page between the 256th and the 511th byte
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.
• BITADDR1: corrupted Bit Address in the page between the 256th and the 511th byte
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.
Using ECC-H code, one bit correction per sector of 512 bytes (MD.TYPECORREC=0b010)

• NPARITY1: Parity N
Parity calculated by the ECC-H.
• WORDADDR1: Corrupted Word Address in the page between the 512th and the 1023th byte
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.
• BITADDR1: Corrupted Bit Address in the page between the 512th and the 1023th byte
During a page read, this field contains the corrupted bit offset where an error occurred, if a single error was detected. If multiple
