10.4.4. 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.

Accesses to syndrome bits are not supported by the conventional memory access through the memory slave interface and instead, the ECC encoder handles them automatically.
