For the CAN transceiver to enter Off-Line mode from On-line or On-line Listen mode a minimum time without bus activity is needed. This
minimum time t
In case of an RXDC / TXDC interfacing failure the CAN transmitter is disabled without setting CTC. Recovery from such a failure is
automatic when CAN communication (with correct interfacing levels) is received. Manual recovery is also possible by setting and
clearing the CTC bit under software control.
