Selecting specific wake-up interrupt

dp05 — Mon, 22 Apr 2013 21:54:11 GMT

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.

For others in a similar situation: after again reviewing my configuration I think the issue was that I enabled the LPTMR interrupt. If I disable the interrupt the hardware trigger to the ADC continues to work and the core only wakes up on an ADC interrupt.

Does this mean your problem is solved?

Thank you very much for sharing! :smileygrin:
