Description | ECC On-Off Control |
This register determines if the ECC checking should be enabled. ECC checking should normally never be disabled. However, in the case where the block 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 block RAM contents.
