MCU wakeup from sleep by a timer

[enkavak]

Hello,

       I am using nRF52832 IC with softdevice and SDK v15.

       I wish to make the MCU in sleep mode and then a couple of milliseconds (let's say 250ms) wakes up the MCU. For this purpose, can I use the timer? Or do you have any idea ?

What is the state of the RTC2's register after you've configured, enabled, and started it?

[enkavak]

yes, enabled and started.

I need the content of the RTC2's registers...

With a prescaler value of 4095dec you will get an RTC frequency of 8Hz (32768Hz / PRESCALER + 1), and with a compare value of 100 000dec you will not trigger an event until 3,5 hours (100 000 ticks/ 8Hz * 60s * 60m) have passed...
