17.6.4 Parity Register 0
Name: PR0
Access Type: Read-only
Offset:0x00C
Reset Value: 0x00000000
Using ECC-H code, one bit correction per page (MD.TYPECORREC=0b000)
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.
• WORDADDR: Word Address
During a page read, this field contains the word address (8-bit or 16-bit word, depending on the memory plane organization)
where an error occurred, if a single error was detected. If multiple errors were detected, this field is meaningless.
• BITADDR: Bit Address
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 256 bytes (MD.TYPECORREC=0b001)
