22.7 Registers for 1 ECC per 256 bytes for a page of 512/2048/4096 bytes, 8-bit word
22.7.1 ECC Parity Register 0
Name:ECC_PR0
Access: Read-only
Once the entire main area of a page is written with data, the register content must be stored at any free location of the
spare area.
• BITADDR0: corrupted Bit Address in the page between the first byte and the 255th bytes
During a page read, this value contains the corrupted bit offset where an error occurred, if a single error was detected. If
multiple errors were detected, this value is meaningless.
• WORDADDR0: corrupted Word Address in the page between the first byte and the 255th bytes
During a page read, this value contains the word address (8-bit word) where an error occurred, if a single error was
detected. If multiple errors were detected, this value is meaningless.
