    RTC with external non-crystal clock




      Since there is no clock input on the the RTC component, can I possibly use a 1pps input on a digital pin as the source for the RTC interrupt?


      Somehow I clicked on the RTC ISR in the Interrupts tab of the design wide resources and it brought up RTC_v1_6.cysch. If I modify this, will I break all further RTC designs (since it seems to be in the component library)


      Alternately, is there a way of providing an external 32.768 kHz external clock this resource can use?
