CMSIS-DAP on-chip

I’m currently using an IC that has a USB port, but I don’t need it. Would it be possible to have the USB port run CMSIS-DAP so I can have debugging support with only 1 IC? How would I get started with interacting with the SWD channel from within the MCU itself?

Bit late reply, but no, you need to have a Dedicated DAP chip.
