4.2 cJTAG Usage

The F280049C MCU supports the cJTAG 2-pin debugging interface, but the onboard XDS100v2 emulator does not. To experiment with cJTAG, an external emulator must be connected through the baseboard. To enable cJTAG:

  1. Connect an external emulator to the controlCARD's baseboard.
  2. Change S4 to the cJTAG position (switch flipped up).
  3. If cJTAG is used, the F280049C MCU will have two additional GPIOs which can be used by the application. Configure S2 and S3, as desired, to control which controlCARD fingers or pins the newly available GPIOs are connected to.
