https://devzone.nordicsemi.com/f/nordic-q-a/17530/dap-electrical-specificationHello, I&#39;m looking for details on the nrf52 DAP signals SWDIO and SWDCLK. Such parameters als min. time high, low to Z, clock duty, maximum frequency, minimum frequency etc. Are these parameters documented anywhere? kind regards and thanks in adven-USTelligent Community 13Sat, 05 Nov 2016 12:25:32 GMThttps://devzone.nordicsemi.com/thread/67397?ContentTypeID=1Sat, 05 Nov 2016 12:25:32 GMT137ad170-7792-4731-bb38-c0d22fbe4515:b6aea8e1-d68e-4978-9355-05221eabc99cTorsten Robitzki<p>Thanks a lot.
