I flew the original ATR72 in the nineties and had an engine failure on takeoff.
I don't know about the -600 and it is a long time ago now but on the original it would have auto feathered the prop and up trimmed the power on the good engine (before you did the climb sequence).
In my failure there was a problem with water getting into the electrics somewhere in the prop control system (where I think the signal came from for the auto feather and up trim) so neither auto feather or uptrim happened for me. Aircraft performance was not exactly great until we feathered the prop...
