Wake up from deep sleep using LPCOMP

[Judge]

Hi everyone, I have the following problem: I want to use LPCOMP to wake the nrf52840 from a deep sleep so how should I use it?

Hi Dmitry,can you give me some examples of that external RTC circuit?

Here you can find a lot of RTC ICs with up to 500 nA current in timekeeping mode.
