The CME-12B32 provides a low-cost software development and debugging system using the D-Bug12 Monitor. The Monitor allows you to locate code in the On-Board RAM, set Break Points, Trace, display / modify registers and memory. When code development is complete, you may relocate the code and program the 32kB Flash EEPROM for dedicated operation. No additional hardware or software is required.
