No, you've got them backwards. Inserting LPM4_EXIT into your
ISR will put you in the LOWEST power mode (CPU Off, Oscillator Off) when
the ISR exits.
If you never use low power mode, then you never need to use the
LPMx_EXIT feature anyway.

Good to know. I'm operating kind of blind here - and, as I indicated, I'm
completely new to Embedded programming (at least of this kind.)
