https://devzone.nordicsemi.com/f/nordic-q-a/26838/spi-configuration-on-nrf52832Hi, Dear Nordic experts: I encountered with a couple of *** issue while configuring SPI port on nRF52832 with PCA10040 demo board. Here I wrap up as below: First, I tried to enable both TWI0 (master) and SPI0 based on the example project &quot;spi_pca1004en-USTelligent Community 13Mon, 13 Nov 2017 08:47:51 GMThttps://devzone.nordicsemi.com/thread/105491?ContentTypeID=1Mon, 13 Nov 2017 08:47:51 GMT137ad170-7792-4731-bb38-c0d22fbe4515:70ad1bfd-a584-4672-b196-795908ceeabbJ&#248;rgen Holmefjord<p>From the section <a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.nrf52810.ps/memory.html?cp=2_2_0_3_1_3#topic"><em>Instantiation</em></a>, you can see that TWIM0 and SPIM0 does not share same ID/base address on nRF52810.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/105490?ContentTypeID=1Mon, 13 Nov 2017 08:14:59 GMT137ad170-7792-4731-bb38-c0d22fbe4515:13ce1f1b-0dfd-44c0-a206-4dedd6bedbd4Samuel Zhang<p>Got it. Also share with your my another finding: you can use both TWI0 and SPI0 in 52810.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/105489?ContentTypeID=1Mon, 13 Nov 2017 04:33:55 GMT137ad170-7792-4731-bb38-c0d22fbe4515:b88bdd7b-b838-444c-bcf7-c72ae737704bRK<p>you can&#39;t use SPI0 and TWI0 at the same time because they share a periperal id, ie they are at the same location in memory. You have to use SPI0 and TWI1 or another combination.</p> <p>See the section in the manual about &#39;Peripherals with shared ID&#39;</p><div style="clear:both;"></div>
