Cygnal µVision2 Debugger Support
Keil Software and Cygnal Integrated Products have joined forces to
provide users with a start-of-the-art development and debugging
platform for the Cygnal C8051F family of mixed-signal,
System-on-a-Chip MCUs. A new µVision2 driver allows the
µVision2 Debugger to communicate with Cygnal's JTAG-based
on-chip debugging logic via the Keil Debugger
Advanced Generic Debugger Interface (AGDI) which is implemented
via a DLL that you plug-in to µVision2.
This new driver allows you to use the µVision2 Debugger to
download your program to your target hardware, start and stop program
execution, set breakpoints, watch variables and memory, and
single-step through your programs. An in-system FLASH programmer
(built into the driver) allows you to rapidly update target code.

JTAG Debugging
The Cygnal JTAG-based on-chip debug logic uses no system
resources: no code memory, RAM, interrupts, timers, serial ports, or
run-time overhead are required. Hardware control (start/stop
execution) is always available.
You need not relocate your program code nor make hardware changes
to debug on your target system. The Cygnal JTAG interface and the
Keil µVision2 Debugger allow you to debug your actual program
in real-time using production target hardware.
