Hm, seems that info is not in the datasheet yet. I remember the accuracy is something like +/- 5%, so not super accurate. I poked the docs team to add this to the chip datasheet. Thank you for clarifying and requesting that it be added to the datasheet. Hopefully, they will do so soon so that no on...

I know that using an external RTC or an external crystal is the most accurate, but perhaps the internal RTC is accurate enough for my purposes. On this page, i...
