Hi

It was not clear from the datasheet, but is the TAMPFREQ register only applicable when using level detection and not edge detection?

I am asking as PC13 (RTC_TS) is not available on some low pin count packages and was thinking RTC_TAMP2 with TAMPTS set could work.

Thanks

From some testing, it would seem TAMPFREQ does not have an effect when using edge triggering.
