An integrated circuit (IC) employs error codes based on fields of data for protecting data transferred from a first circuit to a second circuit on the IC. Each bit of a generated error code is based on one or more fields of the data rather than on consecutive signal bits of a bus. Upon receiving the data in a second circuit, the error code is employed to determine whether the data has been transferred without an error. In case of an error, a response circuit generates an error signal having an error type corresponding to the data fields in which errors are detected. In some examples, the transferred data comprises a transaction request and the error signal indicates whether the transaction request has failed, the transaction request may be retried, or the transaction request may be completed despite the error.
