14.6.3. Indirect Memory Access

The register slave interface on an ECC controller allows software to access the memory block indirectly.

Through this interface, software can alter the memory data content and the stored ECC syndrome bits. By directly altering the data and syndrome bits, software can manually correct corrupted data, and run tests and diagnostics on the ECC controller.

The conventional memory access through the memory target interface does not support accesses to syndrome bits. Instead, the ECC encoder handles them automatically.
