System and method for transparent register data error detection and correction via a communication bus

An integrated circuit comprising:

• a communication interface configured to be coupled to a communication bus;
• a first circuit configured to be coupled to the communication bus;
• and
• a parameter safe storage circuit configured to be coupled to the communication bus, the parameter safe storage circuit comprising a memory and being configured to:
• detect in the communication bus a write command to the first circuit, the write command comprising a write address and write data;
• compare the write address with a set of predefined addresses;
• when the write address matches a predefined address of the set of predefined addresses,
• generate an error correction code (ECC) based at least on the write data, and
• store the ECC in the memory and not in the first circuit;
• detect in the communication bus a read command to the first circuit, the read command comprising a read address and read data;
• compare the read address with the set of predefined addresses;
• and
• when the read address matches a predefined address of the predefined addresses,
• determine whether the read data is corrupted based on the stored ECC provide an error notification in response to determining that the read data is corrupted.
