https://devzone.nordicsemi.com/f/nordic-q-a/94269/52840-uartHi Excuse me: 52840 has UART, UARTE0, and UARTE1. Can the three instances be initialized at the same time thanks!en-USTelligent Community 13Fri, 25 Nov 2022 14:24:02 GMThttps://devzone.nordicsemi.com/thread/397675?ContentTypeID=1Fri, 25 Nov 2022 14:24:02 GMT137ad170-7792-4731-bb38-c0d22fbe4515:7ce16e0f-8842-4b68-944e-9d0add6137a7Allen_<p>好的，非常感谢<span class="emoticon" data-url="https://devzone.nordicsemi.com/cfs-file/__key/system/emoji/1f609.svg" title="Wink">&#x1f609;</span></p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/397672?ContentTypeID=1Fri, 25 Nov 2022 14:11:10 GMT137ad170-7792-4731-bb38-c0d22fbe4515:75f09487-c158-46c5-addf-7b7b3388aa36Einar Thorsrud<p>UART0 and UARTE0 use much of the same HW resources and cannot be used at the same time. However, UARTE1 is independent and can be used at the same time as UART0/UARTE0.
