Selecting specific wake-up interrupt

I am using the KL25 platform for a low-power application. The LPTMR triggers a hardware trigger for the ADC in VLPS and the ADC comparator initiates an interrupt when the sampled value is above some threshold. I'd like to keep the system in VLPS and only wake up into VLPR or Run for an ADC interrupt only. Is there a way to indicate which interrupt sources can wake up from a low-power mode? At the moment it looks like the LPTMR interrupt that triggers the ADC is also triggering a core wake-up.
