After entering the bus-off condition, the CAN controller automatically disables itself just as if the application had called CANDisable(). To exit the bus-off condition, the application must call CANEnable() and then wait for the CAN_STATUS_BUS_OFF condition to clear. If the bus-off
condition does not clear, then there is likely some physical condition or bit timing issue causing the controller to be unable to function properly. There is no way to shorten this sequence as this is the method for recovering from a bus-off condition specified in the CAN 2.0 specification.
