https://devzone.nordicsemi.com/f/nordic-q-a/16220/sdk-v12-nrf_spim_event_clearHello, I was just checking for differences between SDK v11 and v12, more specifically, the differences in the SPI HAL and driver code. In hal\nrf_spim.h of the v12 SDK I&#39;ve found the following code: __STATIC_INLINE void nrf_spim_event_clear(NRF_SPIM_Typeen-USTelligent Community 13Tue, 06 Sep 2016 12:28:06 GMThttps://devzone.nordicsemi.com/thread/61946?ContentTypeID=1Tue, 06 Sep 2016 12:28:06 GMT137ad170-7792-4731-bb38-c0d22fbe4515:9228a9af-2f5a-4d32-b81e-885308192ce6RK<p>It probably got put in SDK 12 because I remember at least one post complaining the SDK didn&#39;t follow the spec and read the registers after they were written. So it&#39;s a bug fix.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/61945?ContentTypeID=1Tue, 06 Sep 2016 12:26:35 GMT137ad170-7792-4731-bb38-c0d22fbe4515:64ec1e0b-8871-478d-894c-bb7d2c692a6eNewtoM<p>Okay, thanks for the answer, RK. It brings up two issues, though: 1. Why was it inserted first in SDK v12? 2. It would have been useful if the SDK developers added a comment for this particular code.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/61944?ContentTypeID=1Tue, 06 Sep 2016 11:15:58 GMT137ad170-7792-4731-bb38-c0d22fbe4515:84cfdc7d-0c4f-40b7-82d9-2d27deb42ee3RK<p>Read the nRF52 documentation - that tells yot that after you write a register you should read it back in order to ensure the write (which can be buffered) is complete.</p><div style="clear:both;"></div>
