11.5.1 User Configuration

The User Configuration values exist in the USER CFG page of CFM Flash Memory. Because this Flash memory uses ECC the Sequence Number the User Configuration must exist in separate Flash words. This is because they are often not written during the same programming sequence but ECC requires a 256-bit Flash word to be written once only. The user configuration register names correspond to Flash addresses as follows:
