Just because if you divide 32.768 KHz by :</P><P></P><P>2,4,8,16,32,.....1024, 2048,...,32768&nbsp; .you always get an integer value.</P><P></P><P>32.768 Khz/32768 = one exact second</P><P>Regards,</P><P></P><P>Luis</P></BODY></HTML> Thu, 28 Feb 2013 09:26:49 GMT https://community.nxp.com/t5/Kinetis-Microcontrollers/I-am-using-32-768KHz-crystal-on-XTALs-for-RTC-application-Why/m-p/277475#M10055 LuisCasado 2013-02-28T09:26:49Z
