            Description

            The master is not able to stop the bus when no valid frames are received. Under some conditions the bus (including all/some slaves) will remain in OPERATIONAL.
            -Error generator or defect cable produces massive frames losses
            -Last slave becomes attached to a switch
            -Switch placed between master and first slave, cable between slave and switch is removed. Bus stop is delayed until valid frames are received again.
            Master shall be able to stop the bus correct, ChannelInit is affected to (stops internally the bus).
