 I&amp;#39;m trying to control the LF clock source on a BL653 (or BL653 DVK), NCS v1.9.1, using &amp;quot; NRF_CLOCK-&amp;gt; LFCLKSRC = 1 &amp;quot; but the clock does not start with this configuration.

&lt;p&gt;You are not suppose to change this from the application, but it&amp;#39;s set through kconfig (at it can&amp;#39;t be dynamically changed run-time). The two you have to choose from are&amp;nbsp;CONFIG_CLOCK_CONTROL_NRF_K32SRC_RC or&amp;nbsp;CONFIG_CLOCK_CONTROL_NRF_K32SRC_XTAL.&lt;/p&gt;
