Tracedata Pin Configuration on nRF52832

I am a newbie and making my way slowly on the NRF52832.

I have the device working as an Eddystone beacon and I also some Basic BT functionality

I have three LED’s connected to the Tracedata Pins

P.015 (TRACEDATA[2])

P.016 (TRACEDATA[1])

P.017 (TRACEDATA[0])

I can’t seem to toggle the LED’s as I assume I need to configure the Traceconfig register. Does anyone know how to do this?
