https://devzone.nordicsemi.com/f/nordic-q-a/13725/sdk-11-spi-slave-bugHi, I think there is the bug in SDK11 Spi slave protocol.

But let us continue the discussion about your second concern in <a href="https://devzone.nordicsemi.com/question/79245/sdk-11-spi-slave-register-return-wrong-tx-value-when-buffer-set-to-0/">the post you created here</a>.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/52450?ContentTypeID=1Wed, 11 May 2016 03:56:27 GMT137ad170-7792-4731-bb38-c0d22fbe4515:c817b650-f999-44fb-b6ec-86f8722b1ebeutrank00<p>If I set the tx buffer to 0, I expect the AMOUNTTX to be 0 when the transfer complete. But intstead, the AMOUNTTX always equal the the AMOUNTRX when the transfer complete. I think this is still a bug.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/52449?ContentTypeID=1Tue, 10 May 2016 07:58:40 GMT137ad170-7792-4731-bb38-c0d22fbe4515:98e30ec8-8c54-40fc-9561-2d1d51865b40Jorge<p>This is an already known <a href="https://devzone.nordicsemi.com/question/66537/spi-slave-problem-with-buffers-nrf51-sdk-v10-bug-in-nrf_drv_spis_event_t-structure/?answer=67584#post-id-67584">bug</a>.</p> <p>You can follow or read <a href="https://devzone.nordicsemi.com/question/71366/what-are-sdk-1100-known-issues/">this page</a> for other bugs that exist on the SDK 11.</p><div style="clear:both;"></div>
