    Page 63 of the reference manual RM0006 dated April 2008 (that is 13742.pdf) refers to the output JRTCLK being controlled by the RTCSEL signal.

    I can find very little info on how the JRTCLK signal is used and nothing on the RTCSEL signal.

    Can anyone help?

    My target is to successfully use the device without the RTC crystal.

    Hi,

    the RTCSEL is the RTC calibration output selection.

    which is drived by ''C'' bit in ''RTC_CR'' register.

    Kind regrads,
