Including external RTC having NRF52832

[AMMUZ BOI]

Hi, I am currently working with the NRF52832 on a custom board that is working with a timer for a particular sleep interval now I have added an external RTC module, and i want to remove that timer from the program , What should I include in the program to integrate this external RTC?

Hi Ebin, 
Could you let me know what's the purpose of having an external RTC instead of using an internal one ? 
It may draw more current when using external RTC and the external RTC add extra cost. 
Do you use the radio  ? If you do, there is a big chance that you are using one of our radio's stack for example BLE. It's unfortunately not possible to configure the stack to use external RTC. 
As mentioned by Louis, please provide more information about the RTC you want to use.
