Transmission Failure Detection

There is a failure detection unit integrated to ensure also a stable functionality during the integrated coreless

transformer transmission. This unit decides wether the transmitted data is valid or not. If four times serial data

coming in from the internal registers is not accepted, the output stages are switched off until the next valid data is

received.
