    • If your application program puts the XC167 device in Power Down or Idle mode, the OCDS in the Infineon XC167 device (and subsequently the ULINK) stops working. Therefore, do not put the XC167 device device into the power saving modes during the software development cycle.
  2. Power up the MCBXC167 Board.
  3. Configure the Debugger in the Project - Options for Target - Debug dialog.
