31.1.6 ECC Support

The FCW always writes ECC values for Double Word, Quad Word, and Row Write operations. The FCW always writes Parity for Single Write operations. The Flash ECC settings (in FCR ECCCTRL) determine if Single Write operations are allowed. Single Write operations are NOT allowed when Flash ECC settings are set to ECC Writes with ECC Reads. For all Dynamic Write ECC selections, the FCW allows Single Write operations.

Note that the Width of the Flash determines if Single, Double or Quad word programming is supported. See the Control Operation Register (CTRLOP) for flash operations supported for each flash bit width.
