Why the unused bits in the register change to 1 |
Hello 曾经怀念,
I hope all is great with you. Thank you for using the NXP communities.
Please note that the “X” means undefined. I mean, they might be logic 1 or 0. Such values are not relevant for the behavior of the device.
Is you RTC working as expected?
Regards,
David
