Bus Start Test
During documentation updated and Protocol Control review, it was discovered that after 11 recessive bits PC_Control switches to "inteframe" state, intermission part. This might cause the fact that directly after this switch, SOF will be interpreted as Overload condition.
IMO interframe state should go directly to "intermission idle" state.
It might be good to examine this possible issue and add test in which one node will join active communication. This can be done in feature tests where only one frame will be sending frames with STM mode and other node will be Enabled when frame is in progress!
