https://devzone.nordicsemi.com/f/nordic-q-a/645/how-to-identify-nrf58122-over-swdIs there a register, accessible via the SWD-DP and present across ARM devices, that I can use to distinguish the nRF51822 from other microcontrollers?

Even SEGGER JLinkLite finds out that there is a Cortex M0 processor but can&#39;t find out which micro-controller. Best of luck with McHck!</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/3296?ContentTypeID=1Mon, 14 Oct 2013 12:53:08 GMT137ad170-7792-4731-bb38-c0d22fbe4515:ac08827d-aa49-4012-84ae-000b3dd21130Christopher Mason<p>I was kind of hoping there would be a builtin ARM register or entries the ROM Table that would be present across all ARM CPUs. Right now I&#39;m using CPUID and IDR but I think this is only specific to Cortex M0, not to Nordic or NRF51822.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/3295?ContentTypeID=1Mon, 14 Oct 2013 11:45:50 GMT137ad170-7792-4731-bb38-c0d22fbe4515:79ca01f3-0608-46d1-ac2e-4d0b1c37338fJanek Mann<p>How about FICR-&gt;CONFIGID? Perhaps combined with some other values from FICR to minimise risk of false positives.</p><div style="clear:both;"></div>
