But in nRF51822_PS_v2.0, the max bit rates for SPI master change to 4Mbps(section 8.9, page47) May I know why? And I still can find 8Mbps optionen-USTelligent Community 13Fri, 22 Nov 2013 16:08:56 GMThttps://devzone.nordicsemi.com/thread/4614?ContentTypeID=1Fri, 22 Nov 2013 16:08:56 GMT137ad170-7792-4731-bb38-c0d22fbe4515:52ad5cf2-82c2-4335-a0f0-743a1c9d7477Petter Myhre<p>Hi</p> <p>There are is a combination of different aspects that led to the decrease from 8Mbps to 4Mbps.</p> <p>The 8Mbps is an error, and should be corrected, thank you for making us aware.</p> <p>Configuring the SPI to 8Mbps will be out of spec, so we can&#39;t guarantee the correct behavior.</p> <p>Sorry for the inconvenience.</p><div style="clear:both;"></div>
