When using the internal RC oscillator, the RTC in the PMIC appears to loose 1-2 seconds every few minutes; The output frequency is 32.0kHz as expected per the datasheet.
After installing the 32.786kHz external crystal, and clearing the CK32K_CTRL bit, the time is spot on.
After reading the datasheet and forums, can I get a definitive answer to:
Is there a way to run the RTC off the internal oscillator without gross inaccuracies?
Is there a way to base it on the 32.0kHz internally generated clock?
Does it REQUIRE a 32.786kHz external crystal in order to be of any usefulness?
Thanks,
