 With an nRF9160 based project and lowest power, lowest current consumption in mind, is there an explicit I/O pin setting to make via Zephyr API for the nRF9160 pins COEX0, COEX1, COEX2, AUX, MAGPIO0, MAGPIO1 and MAGPIO2?

&lt;p&gt;&amp;nbsp;&lt;/p&gt;
&lt;p&gt;If you do not use any of these pins, you can leave them as-is. The modem will take care of their default state to ensure low power.&lt;/p&gt;
&lt;p&gt;However, if they are in use, you should follow the recommended handling. Please note this line for the used COEX pins in your design, in chapter 4.16 in the nwp_037 that you linked to:&lt;/p&gt;
&lt;p&gt;&lt;pre class="ui-code" data-mode="text"&gt;Therefore, it is mandatory to use external pull-down resistors in the size range of 100 kΩ in the COEX interface.&lt;/pre&gt;&lt;/p&gt;
&lt;p&gt;&amp;nbsp;&lt;/p&gt;
&lt;p&gt;Kind regards,&lt;/p&gt;
&lt;p&gt;Håkon&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
