Start/Stop - stopping the Tx side of an RT to RT broadcast transaction does not stop the Rx side

[douglasnorman]

Is your feature request related to a problem? Please describe.
If the Tx side of an RT to RT Broadcast transaction is stopped, the Rx side does not stop. Instead the Rx side values change to something other than the last sent from the Tx and the timestamp continues to increment.

Describe the solution you'd like
This does not necessarily need a solution. We suspect this happens because the Bus Controller is still communicating with the Rx side telling it to receive. Note that this works as expected if the BC is stopped.

Describe alternatives you've considered
Do nothing - it's an expected "feature".
