Start/Stop Debug Button Use the Start/Stop Debug Session toolbar button or the µVision command Debug - Start/Stop Debug Session to connect the debugger to the Keil ULINK Adapter. The CPU stops and connects to the On-Chip Debug System (OCDS) of the Infineon XC167 device. For details on the debugging features, refer to the µVision User's Guide.


  • Debugging the BLINKY program using the µVision debugger requires a ULINK USB-JTAG adapter.

The Peripherals Menu allows you to open different dialogs for Peripheral units on the Infineon XC167 device. You may view and/or change the state and configuration of on-chip peripherals using these dialogs. For example:

The PORT 3 dialog reflects the status of the I/O ports.
