DRV8714-Q1: use one DRV8714 to drive three motor

Hi Expert,

I see that one DRV8714 can drive three motor mentioned in below post. I have several question about this usage.

1. Can motor1 and motor 2 run at the same time?
2. If motor2 is free running and now I want to drive motor 1 or 3, is there any current flow conflict in the common half-bridge? I suppose it’s related with “make sure that the appropriate bridges are in Hi Z state when needed”. But I don’t figure out the details and how to apply the scheme properly

Thanks.
