And with Cygnal Parts you cannot beat the low entry cost. $99 gets you an eval board, am assembler / linker from Keil and the JTAG adapter for connection to PC serial port. The PC based IDE supports FLASH programming via this cable as well as debug capability to run, single step and use breakpoints on the program....BREAKPOINTS ARE HARWARE FEATURE OF EVERY CHIP THAT FUNCTION WHILE THE REAL APPLICATION CODE RUNS DIRECTLY FROM FLASH AT FULL SPEED.

I LOVE THESE PARTS !!
