 We are using the npm1300 PMIC to run the nrf5340 VDD at 1.8V. If we connect D+ and D- from the USB port directly to the D+ and D- pins, will the USB peripheral of the nrf5340 still work?

Thus they run fine at 1.8V VDD.&lt;/p&gt;
&lt;p&gt;See the USB chapter in the PS for details.&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
