How to enable SWO Interrupt stats K64F

I am trying to enable the SWO on my FRDM K64F board.  I am able to connect to the mcu with my multilink FX fine with the SWD protocol.  The issue I am having is that I can not get the SWO features to work.  I have setup the SWO pin using the config tool as follows:

 

/* PORTA2 (pin 36) is configured as TRACE_SWO */
PORT_SetPinMux(PORTA, 2U, kPORT_MuxAlt7);

 

When I connect with the P&E multilink all of the SWO options are grey and none of those options work.  Is there anything else that needs to be done in order to get the SWO to output the interrupt statistics?  I have searched and how not found much information.  Thanks in advance.
