Can I use 3xSPIM, 1x UARTE and 1x TWIM simutaneously on NRF5340?https://devzone.nordicsemi.com/f/nordic-q-a/77851/can-i-use-3xspim-1x-uarte-and-1x-twim-simutaneously-on-nrf5340Hi all, In my project, I make 2 SPIM and 1 UARTE works well. Currently I want to use 1 TWIM, so I add lines below in proj.conf However, I get errors: gen_isr_tables.py: error: multiple registrations at table_index 9 for irq 9 (0x9) I wonderen-USTelligent Community 13Mon, 26 Jul 2021 08:18:22 GMTRE: Can I use 3xSPIM, 1x UARTE and 1x TWIM simutaneously on NRF5340?https://devzone.nordicsemi.com/thread/321722?ContentTypeID=1Mon, 26 Jul 2021 08:18:22 GMT137ad170-7792-4731-bb38-c0d22fbe4515:29ffbe1d-de48-4815-8ea2-a8e6bcc78692J&#248;rgen Holmefjord<p>Hi,</p> <p>The serial peripherals (UARTE/SPIM/SPIS/TWIM/TWIS) in nRF5340 shares resources and base addresses, which means that you can only enable one type of peripheral for each slot.</p> <p>From&nbsp;<a title="Peripheral instantiation" href="https://infocenter.nordicsemi.com/topic/ps_nrf5340/chapters/memory/appmem.html?cp=3_0_0_4_2_0#instantiation">Peripheral instantiation</a>, you can see which peripherals share base address. Make sure you only enable one peripheral for each. For instance:</p> <ul> <li>UARTE0</li> <li>TWIM1</li> <li>SPIM2</li> <li>SPIM3</li> <li>SPIM4</li> </ul> <p>SPIM4 (32 MHz high-speed instance) does not share base address with other serial peripherals, and can only be used for SPIM.</p> <p>As you can see, the combination you request should fit exactly into the supported instances in nRF5340 if you configure it correctly.</p> <p>Best regards,<br />Jørgen</p><div style="clear:both;"></div>
