Well, actually it doesn't (well.. didn't work on _my_ ti, with the di 
instruction (so the "on-button interrupt" is probably maskable...)...
but my original question was how to turn the power off _the way TI does 
it_... And I _do_ suppose this includes turning to low-power mode... If 
it doesn't then what's the point of a low-power mode?
