I'm working with a SAD51N20 with a custom board. The RTC work with the ultra low power internal oscillator. The rtc is configured to work in mode 0.
I have initialized the rtc and one compare alarm.
Everything work properly in run-mode, idle and stand by.
when the time reach the alarm the interrupt is asserted i the application is in stand by or idle the application is waked up.
If I put the application in hibernate when the compare value is reached the application reset.
I have read the user manual and it seams that rtc have to work also in hibernate mode
Can you give me any sudgestion?
