Hello, I want to know how to operate RTC With WDT.
At first I use PRoc BLE with the example those name is RTC_P4_WDT example.
I found some weird thing that is about RTC.
To make exact alarm, I executed that example by modifying Alarm Time.
first thing was modifying alarm Date ( from 04:01:30 to 02:59:59, Start time - 02:59:50).
result was malfunction routine. Alarm was not working.
compared to past experiment, second thing was modifying alarm date (from 04:01:30 to 04:01:01)
result was correctly working.
so I want to know why this result is happening.
(PS,) the result of experiment is that Between Alarm time and Time, the gap have to has more than one minutes.

Hi,
The Alarm can be set only in minutes level, not seconds.
If you want it to be in seconds, then you can use the timer components to generate timer interrupts.

and I want to know the sequence of the RTC. As you know, the time which is at 2:59:59 changes 04:00:00 after 1 second.
so, I wonder if RTC operates correctly in a day. and I want to know how long RTC uses, such as 2 years, 4 years .....
