ST620x ST621x ST622x ST625x ST

This development tool is able to emulate all components belonging to the ST620X/1X/2X, ST625X/6X and to ST629X family.
The dedication board is common for emulating the three families.Tthe choice of emulated ROM Device is made by properly setting the configuration
on the dedication board, and connecting the appropriate PROBE on the appropriate connectors.
