What do you mean be "calibrate the week"? Do you mean set the day of the week?

Hello. 

Thanks for your support first!

They only want the data of year/month/day/ and the clock data(exact time, minute and second), skip setting the week when setting and initializing time, will it affect the normal calendar display?

Thanks and regards,

Hi Cherry,

Suggest to initial the week register although customer don't use the week information because that is make sure that after the initialization the value of the RTC register is within the specified range. Writing of invalid date or time information or data values outside the legal ranges specified in the RTCSEC, RTCMIN, RTCHOUR, RTCDAY, RTCDOW, RTCYEARH, RTCYEARL, RTCAMIN, RTCAHOUR, RTCADAY, and RTCADOW registers can result in unpredictable behavior.

Hi Allen,

That is, when the initialization week data is within the register range, it will be ok, right? And it won't affect the actual display of week and clock?

Thanks and regards,

Cherry
