On-Chip Debug Circuitry
The C8051F41x devices include on-chip Silicon Laboratories 2-Wire (C2) debug circuitry that provides
non-intrusive, full speed, in-circuit debugging of the production part
installed in the end application.
Silicon Laboratories’ debugging system supports inspection and modification of memory and registers,
breakpoints, and single stepping. No additional target RAM, program memory, timers, or communications
channels are required. All the digital and analog peripherals are functional and work correctly while debug-
ging. All the peripherals (except for the ADC and SMBus) are stalled when the MCU is halted, during single
stepping, or at a breakpoint in order to keep them synchronized.
The C8051F410DK development kit provides all the hardware and software necessary to develop applica-
tion code and perform in-circuit debugging with the C8051F41x MCUs. The kit 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 com-
puter with Windows
®
98 SE or later 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 application 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.
