includes software with a developer's studio and debugger, a USB debug adapter, a target application
board with the associated MCU installed, and the required cables and wall-mount power supply. The
development kit requires a computer with Windows installed. As shown in Figure 1.5, the PC is connected
to the USB debug adapter. A six-inch ribbon cable connects the USB debug adapter to the user's applica-
tion board, picking up the two C2 pins and GND.
The Silicon Laboratories IDE interface is a vastly superior developing and debugging configuration, com-
pared to standard MCU emulators that use on-board "ICE Chips" and require the MCU in the application
board to be socketed. Silicon Laboratories’ debug paradigm increases ease of use and preserves the per-
formance of the precision analog peripherals.
