• CODEWORD:
Once the 512 bytes of a page is written with data, this register content must be stored to any free location of the spare area.
For a page of 512 bytes the entire redundancy words are made of 8 words of 10 bits. All those redundancies words are
concatenated to a word of 80 bits and then cut to 10 words of 8 bits to facilitate their writing in the extra area.
At the end of a page write, this field contains the redundancy word to be stored to the extra area.
