Detecting JTAG (SWDIO/SWDCLK) Connection

[jprofit]

Is there a way for firmware running on the nRF52 to detect the presence of a SEGGER (or other) SWD capable device? I've looked through all the nRF registers but couldn't find anything appropriate.

( ( CoreDebug->DHCSR & CoreDebug_DHCSR_C_DEBUGEN_Msk ) != 0 )

ought to do the trick.
