VCC is normally connected directly to the battery. So no,
you can't control that without unplugging the battery.
Why don't you drive a pin high from the microcontroller to
power your external resistors? Or, if the current
consumption is greater than the MSP430 can supply, use a
GPIO-toggled FET switch to supply current to your
resistors.

Hi,
I have some resistors attached to the Analog VCC output
of my Tmote Sky. Is
there any component that provides the function of
cutting off VCC output?
Otherwise I have to take out batteries every time I
don't use it. The
battery will be drawn out quickly if I leave it on the
Tmote.
Thanks!
