Ok, good. Could be that your debugging is somehow interfering with the LF clock, especially if you place breakpoints, halt the CPU, etc. For lower power consumption, you should switch back to LF RC when you are not debugging.

yes,it is.

Thank you, the change of low frequency clock source to synthesized clock mentioned in this post worked for me. Although I used the internal low frequency clock before.
