 The customer found several issues when testing SPI timing, 
 NRF52832 communicates with the master chip, Qualcomm XR2, through SPI, and NRF52832 serves as the slave.

&lt;p&gt;What numbers am I looking at? The bottom screenshot, is that your measurements? Or is that also from the specification? I will assume that these are your measurements. What application are you running when doing this measurement? Is it one of our examples? Does it do anything other than SPI?&lt;/p&gt;
&lt;p&gt;&lt;/p&gt;
&lt;p&gt;The lines that you have underlined are:&lt;/p&gt;
&lt;p&gt;CSN to MISO disabled, which are the same in both documents. 68ns.&lt;/p&gt;
&lt;p&gt;CLK edge to MISO valid is a bit higher in the bottom array. Is that your measurements?&lt;/p&gt;
&lt;p&gt;BR,&lt;br /&gt;Edvin&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
