Eliminating trace functionality during debug

[Daniel Reisfeld]

Hi,

I'm using custom board with the nrf42840 and I need to use p1.09 as a GPIO. 

How can I do this in a debugging mode (using the PCA10056 as a jlink)? Can I get a code example? 

Thanks,

Daniel

Simon thanks,

I tried NRF_CLOCK->TRACECONFIG = 0; It crashes the program. Can you kindly elaborate how to do it right?
