    Hi Kaka-san,

    Have you looked at the RTC compensation register (RTCDRIFT), Every hour on the hour, a positive or negative number of milliseconds is added to the milliseconds register to compensate for inaccuracy in the 32.768kHz crystal based on the value of COMP[3:0].

    Reference -  4.3.2.20 RTCDRIFT Register - Technical reference manual.

    Hope this helps. Let us know if you have question beyond what is suggested above.

    Regards

    Hi Vasanth,

    Thank you for your response.
    I have informed them but we have not introduced this register for my customers.
    So, I do not know this function will work without any problem.
    Have you ever used this function for customer application?

    Best regards.

    Hi Kaka-san,

    The RTC compensation register should work as defined in the reference manual. If you have additional questions or need clarity on any of these aspects Pl do let us know.
