17.6.7 Parity Register 2 - 15
Name: PR2 - PR15
Access Type: Read-only
Offset: 0x018 - 0x04C
Reset Value: 0x00000000
Using ECC-H code, one bit correction per sector of 256 bytes (MD.TYPECORREC=0b001)
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.
• NPARITYn: Parity N
Parity calculated by the ECC-H.
• WORDADDRn: corrupted Word Address in the packet number n of 256 bytes in the page
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.
• BITADDRn: corrupted Bit Address in the packet number n of 256 bytes in the page
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.
