22.6.2 ECC Parity Register 1
Name:ECC_PR1
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.
BITADDR1: corrupted Bit Address in the page between the 512th and the 1023rd 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.
WORDADDR1: corrupted Word Address in the page between the 512th and the 1023rd 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.
