&lt;p&gt;&amp;nbsp;&lt;/p&gt;
&lt;p&gt;I am being told in theory this might be possible, at least for some/most inbetween values. The reason why it is not documented supposedly because the jitter is worse for these values, and they are left out of the documentation.&lt;/p&gt;
&lt;p&gt;We do not have a formula or similar for calculating the register value based on the required divider. You will have to determine it through trial and error.&lt;/p&gt;
&lt;p&gt;&amp;nbsp;&lt;/p&gt;
&lt;p&gt;Best regards,&lt;/p&gt;

&lt;p&gt;Will the nRF52840&amp;#39;s I2S work with other divider-settings not listed?&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
