Cross-triggering

If you expand the processor entries in the Synch tab, you see the cross-triggering controls:

These controls specify how each of the processors is affected by the others in the group:

In               Indicates whether the processor is stopped by the stop requests of other processors. In the example above, if SimARM_6 hits a breakpoint, SimARM_7 is unaffected.

Out             Indicates whether the processor makes a stop request to the other processors in the group when it stops. In the example above, if SimARM_7 hits a breakpoint, SimARM_6 responds to the Stop request

If neither In nor Out are checked for a processor, it is ignored for cross-triggering.
