On-Chip Debug Circuitry

The C8051F31x devices include on-chip Silicon Labs 2-Wire (C2) debug circuitry that provides non-intru-

sive, full speed, in-circuit debugging of the production part installed in the end application.

Silicon Labs' debugging system supports inspection and modification of memory and registers, break-

points, and single stepping. No additional target RAM, program memory, timers, or communications chan-

nels are required. All the digital and analog peripherals are functional and work correctly while debugging.

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 C8051F310DK development kit provides all the hardware and software necessary to develop applica-

tion code and perform in-circuit debugging with the C8051F31x MCUs. The kit includes software with a

developer's studio and debugger, an integrated 8051 assembler, a debug adapter, a target application

board with the associated MCU installed, and the required cables and wall-mount power supply.

The Silicon Labs IDE interface is a vastly superior developing and debugging configuration, compared to

standard MCU emulators that use on-board "ICE Chips" and require the MCU in the application board to

be socketed. Silicon Labs' debug paradigm increases ease of use and preserves the performance of the

precision analog peripherals.
