Hello NXP,

Does PCA21125T RTC chip has any write protection mechanism for its registers ? If does how to disable it ?

Hello,

The PCA21125T does not have any write protection mechanism for its registers.

Do you have a specific error?

I am having issues while clearing the default values of RTC registers, even I am not allowed to access the Control registers of the chip.
