You can use the sYnch  window, then the synchronization is done by software with about a millisecond delay.

Otherwise, you can get a hardware-based synchronization if the chip supports BDGREQ and DBGACK signals. In this case, you can connect both debug modules over PODBUS and use the commands TrBus.Out Break and TrBus.Set Break for each PowerView instance. Refer for more information to the documentation of these commands in General Commands Reference Guide T.
