RTC Wake up

[bhakti]

I am interfacing external RTC PCF8563 to nrf52840. Also I will be using low power sleep mode. Will it be possible to wake up nrf using 1hr alarm interrupt of rtc?

Thank you for the answer. Also can we use internal RTC alarms for wake up? Does internal RTC of nrf52840 have 1hr alarm register?

Also please share information documents or link related to internal rtc.

Thank you.
