ConnectCore MP15 Hardware Support Question

  1. In the ConnectCore MP15 documentation, what does “MCA” stand for?
  2. Are the MCA pins fixed? Does that include the SWD functionality?
  3. When trying to reassign these pins, what is the associated resource in SmartIO Mux?

Micro Controller Assist (MCA) - Micro Controller Assist (MCA) | ConnectCore 8M Nano

However, on ConnectCore MP15, the MCA is not populated, and there are no plans to create a variant with MCA populated. You can re-use pins assigned to MCA.
