the EFM8UB2 on the kit, the debugger can also be used to program and debug external Silicon Labs EFM32, EFM8, EZR32, and EFR32 devices. The debugger supports three different debug interfaces used with Silicon Labs devices: • Serial Wire Debug, which is used with all EFM32, EFR32, and EZR32 devices • JTAG, which can be used with EFR32 and some EFM32 devices • C2 Debug, which is used with EFM8 devices To ensure accurate debugging, use the appropriate debug interface for your device. The debug connector on the board supports all three of these modes
