78K0R - Cool it!

4. On-Chip debugging

The 78K0R - Cool it! board offers two possibilities to use On-Chip debugging (OCD). The TK-78K0R On-
Board debug function of 78K0R – Cool it! allows On-Chip debugging without a need of external debug
hardware. Within this mode the default USB connection to the Host computer based on the virtual UART
driver is used as debug interface. All standard debug functions are available in the On-Board debugging
mode like FLASH programming / downloading, code execution, single stepping, breakpoints, memory
manipulation etc.
Additionally 78K0R – Cool it! supports the QB-MINI2 On-Chip debug emulator in order to use On-Chip
debug function of the 78K0R/KG3 device. The system configuration for On-Chip debugging is shown in
figure below.
