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

Hi Daniel

The TRACEDATA1-4 pins will be ordinary GPIOs as long as the TRACECONFIG->TRACEMUX field is set to 0, i.e. GPIOs multiplexed onto all trace-pins.

Best regards,

Simon
