SWP communication and still debug?

I am using STM32L4 Nucleo board to develop an aplication which will be using the SWPMI port.


I've been reading around and seems that the debug framework is already using it? So my question would be, how do I use the SWPMI_IO port for communication and still being able to debug.


As seen in the figure the bit SWP_TBYP bit switches the SWP kernel interface.



I guess that if I want to use the SWPMI_IO signal, I would need to debug using an external JTAG interface.
