understanding the exhaust valves opening ?

Hello Fellas,
Just got my M5 this week, and today, i had a quick look at when the exhaust valves are open, and shut etc.I notice they didnt open when stationery, on warm up, with any throttle sport setting, but when i returned, with a hot engine, they were continually open. Do they just open, then stay open, when the car is up to temperature, or am i missing any other settings/openings etc ?, Thankyou, regards, SIMON.
