nRF52832 SAADC: How to monitor ADC pin with certain threshold?

Hello All,

I am just facing an issue w.r.t monitoring the ADC pin with certain threshold voltage. I am able to read the voltage level using SAADC driver on that pin and even can monitor the ADC value using some timers.

But using the periodic timers to monitor the ADC voltage is bit costly on battery! So is there any driver modules or library from nRF to monitor the change in voltage in this ADC pin to trigger the application using callbacks?

Basically saving power is main concern we are facing!
