Conflict between JTAG and GPIO pins, using Processor Expert and FRDM-K64F

I am working on a project that uses some pins available in the FRDM K64F headers, namely PTA0, PTA1, and PTA2. However, when creating a project with Processor Expert and setting up those pins with BitIO components, I ger an error message stating that there is a conflict with the Cpu component. Checking on that component, I found out that these pins are used for the JTAG interface. There is an option to disable those pins, but I am afraid of trying something that may disable debugging, and thus bricking my board.


How can I solve this problem? I suppose that pins PTA0-2 should be available, since they are connected to the board headers.


Thanks in advance,
