Whenever the data is transferred or stored on message ram, there are
inherent risks of it being lost or corruption known as single-bit errors.
ECC constantly scans data as it is processed to the message ram, using a
method known as parity checking and raise the error signals for corruption.
Add error correction code config property to enable/disable the
error correction code (ECC) functionality for Message RAM used to create
valid ECC checksums.
