Mapping System clock on GPIO

Hi all,
I'm working with STM32F3DISCOVERY.
I'm trying to map the system clk on a GPIO to view it with an oscilloscope.
In the following datasheet DM00058181 on page 39 I've found the signal  SWCLK-JTCK that should be the system clock, but I didn't find any information on this signal. 
Do you know this signal?

Thanks and regards
