24.3. Debug Support
Each MCU has on-chip JTAG and debug logic that provides non-intrusive, full speed, in-circuit debug support using
the production part installed in the end application, via the four pin JTAG I/F. Silicon Labs' debug system supports
inspection and modification of memory and registers, breakpoints, and single stepping. No additional target RAM,
program memory, or communications channels are required. All the digital and analog peripherals are functional and
work correctly (remain synchronized) while debugging. The Watchdog Timer (WDT) is disabled when the MCU is
halted during single stepping or at a breakpoint.
The C8051F020DK is a development kit with all the hardware and software necessary to develop application code
and perform in-circuit debug with each MCU in the C8051F020 family. Each kit includes an Integrated Development
Environment (IDE) which has a debugger and integrated 8051 assembler. The kit also includes an RS-232 to JTAG
interface module referred to as the Serial Adapter, a target application board with a C8051F020 installed, RS-232 and
JTAG cables, and wall-mount power supply.
