31.2.8 ECC Support

The FCW always writes ECC values for Quad Word and Row Write operations. The FCW always writes Parity for Single Write operations. The Flash ECC settings only 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 additional information on ECC settings, see Section 3 FCR below. For all Dynamic Write ECC selections, the FCW allows Single Write operations.
