 We measured the SPIS waveform and found some issue on tspis, vso. 
 In nRF52832 v1.4 page 303, the max value of tspis, vso is 19ns but we measured it is around 39ns~49ns and it works well. 
 Have any side effect in this and how to fixed this issue</description><dc:language>en-US</dc:language><generator>Telligent Community 13</generator><lastBuildDate>Mon, 16 Jul 2018 12:51:59 GMT</lastBuildDate><atom:link rel="self" type="application/rss+xml" href="https://devzone.nordicsemi.com/f/nordic-q-a/36334/nrf52832-spis-tvso-timing-issue" /><item><title>RE: nRF52832 SPIS Tvso timing issue</title><link>https://devzone.nordicsemi.com/thread/140205?ContentTypeID=1</link><pubDate>Mon, 16 Jul 2018 12:51:59 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:5bf49f52-3f68-4ef2-a7d1-053339adcbf0</guid><dc:creator>haakonsh</dc:creator><description>&lt;p&gt;Hey Atlas,&lt;/p&gt;
&lt;p&gt;You waveform looks&amp;nbsp;a bit capacitively loaded, it might be that the probes you&amp;#39;re using or another part of the circuit adds a significant&amp;nbsp;amount of capacitance and therefore a longer&amp;nbsp;rise time of the signal.&amp;nbsp;&lt;/p&gt;
&lt;p&gt;I do not know what side effects to expect, but I suggest that you set the GPIOs as high drive at least in logic high (&lt;em&gt;NRF_GPIO_PIN_S0H1&lt;/em&gt;) in order to reduce the rise time.&amp;nbsp;&amp;nbsp;&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: nRF52832 SPIS Tvso timing issue</title><link>https://devzone.nordicsemi.com/thread/140143?ContentTypeID=1</link><pubDate>Mon, 16 Jul 2018 03:40:26 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:73f484e0-5095-43ec-9d99-4a6bba3887bf</guid><dc:creator>Atlas</dc:creator><description>&lt;p&gt;Hi&lt;/p&gt;
