 I&amp;#39;m using NRF52832 and a core adaptation for Arduino IDE. In my project I&amp;#39;m using both TWI and SPI interfaces. If for TWI I manage to reduce the current during sleep from 600 uA to 50 uA (normal for me since I have 2 peripherals running), when I</description><dc:language>en-US</dc:language><generator>Telligent Community 13</generator><lastBuildDate>Wed, 07 Nov 2018 17:40:00 GMT</lastBuildDate><atom:link rel="self" type="application/rss+xml" href="https://devzone.nordicsemi.com/f/nordic-q-a/39897/spi-current-draw-high-after-errata-89" /><item><title>RE: SPI current draw high after errata 89</title><link>https://devzone.nordicsemi.com/thread/156373?ContentTypeID=1</link><pubDate>Wed, 07 Nov 2018 17:40:00 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:f338b445-b4d8-485f-9afb-222af2ef6179</guid><dc:creator>hmolesworth</dc:creator><description>&lt;p&gt;When the SPI peripheral is powered down any of the nRF52832 SPI pins which remain configured as outputs connecting to the peripheral will phantom power the peripheral which in turn sucks power out of those pins. To correct this either revert all the SPI pins to default inputs or simply drive the output pins low (not high).&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: SPI current draw high after errata 89</title><link>https://devzone.nordicsemi.com/thread/156363?ContentTypeID=1</link><pubDate>Wed, 07 Nov 2018 16:04:48 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:6b5bc706-2369-43e0-bc27-7f689093b297</guid><dc:creator>Stian R&amp;#248;ed Hafskjold</dc:creator><description>&lt;p&gt;Have you enabled UART logging?
