This register determines if the ECC checking should be enabled. ECC checking should normally never be disabled. However, in the case where the on-chip RAM ECC bits have not been initialized at startup, they must be manually initialized before enabling the ECC checking. The ECC initialization is done by performing a read followed by a write on the whole on-chip RAM contents.

The register is implemented if C_ECC_ONOFF_REGISTER is set to 1.
