I am trying to wake up my device and service an ADC threshold interrupt (ADC result is greater than a preset threshold) while in low power mode LPM3. My code services the interrupt with no problem if the device is in active mode, but not if the LPM3 bits are set in the SR. I expected to be able to use the ADC and its interrupts in LPM3. Am I mistaken or are there other settings needed to get this to work?
