- /* Software Reset the RTC */
- RTC->MODE2.CTRLA.bit.SWRST = 1;
- /* Wait end of reset */
- while (RTC->MODE2.CTRLA.bit.SWRST);
+ /* DISABLE RTC MASTER */
Thank you for testing!
btw, do we need to call `rtc_poweroff()` and `rtc_reset()` here at all?
e.g. the RTC keeps ticking in HIBERNATE / BACKUP deep sleep mode and can wake the CPU (which triggers a reset).
I was wondering why the RTC was still starting at 0 after that - only to discover that it is being reset in `rtc_init()`!
Is this the intended behavior? If not, I'd much rather just remove those calls here.
