6.7.1.1 Active mode
CAN wake-up filter passed
In the System Diagnosis register two dedicated CAN status bits (CANMD) are available to
signal the mode of the transceiver.
In Active mode the CAN transceiver can transmit data to and receive data from the CAN
bus. To enter Active mode the CMC bit must be set in the Physical Layer Control register
and the SBC must be in Normal mode or Flash 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 for
reactivating the CAN transmitter.
