Hello,

 

please help me by answer to this question:

 

is it possible ( AT32UC3A0512 ) to use external clock as RTC clock source ( xin32 pin ) ? I mean not quartz oscillator but external Square wave source.

 

 

I could not find any information on datasheet. 

 

 

Thanks

Yes.

Section 13.5.3 32 KHz oscillator operation and section 13.6.6 PM 32 KHz Oscillator Control Register.

 

Edit: Pardon the edits, but this actually-the-same-post double post confuses me.
