In case of an RXDC / TXDC interfacing failure the LIN transmitter is disabled without setting LTC. Recovery from such a failure is
automatic when LIN communication (with correct interfacing levels) is received. Manual recovery is also possible by setting and clearing
the LTC bit under software control.
