In Active mode, the CAN transceiver can transmit data to and receive data from the
CAN-bus. The CMC bit in the Physical Layer register must be set and the SBC must be in
Normal or Flash mode before the transceiver can enter Active mode. In Active mode,
voltage regulator V2 is activated automatically.
The CTC bit can be used to set the CAN transceiver to a Listen-only mode. The
transmitter output stage is disabled in this mode.
After an overload condition on voltage regulator V2, the CTC bit must be cleared to
reactivate the CAN transmitter.
On leaving Active mode, the CAN transmitter is disabled and the CAN receiver monitors
the CAN-bus for a valid wake-up. The CAN termination is then working autonomously.
