PP to main in a Trap routine.

Afternoon, 

I was wondering if someone could give me a little bit of insight into how a PP to main would work if a robot was in a trap routine. 

If the robot was in a trap routine waiting for a digital input, and someone was to force a pp to main and start the robots; would this restart the robot currently executing a trap or would it be unaffected by this? 

Thanks in advance for your help!
