3.7 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.
