 1.The customer does not require an external hardware reset circuit. How should the reset pin be handled externally? 
 2. Can R1 and C13 be omitted? 
 3. If R1 cannot be omitted? So, should R1 be left dangling? 
 
 Best regards,

It is about regulatory certificates. So the official recommendation is to keep them and R1 should be connected to VDD of SoC if you are not using it. R1 should not be left floating if you want to keep it (leaving it float&amp;nbsp;does not cause problem but goes against the purpose of having it). Also please note that reset pin already has a permanent pull up resistor.&amp;nbsp;&lt;br /&gt;&lt;br /&gt;Best regards,&lt;br /&gt;Ressa&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
