FEATURES
The DEMO9S12XDT512 is an evaluation or demonstration board for the Freescale
MC9S12XDT512 MCU. Development of applications is quick and easy with the integrated
USB-Multilink BDM, sample software tools, and examples. A standard BDM debug port is also
provided, but not populated, to allow use of an external BDM pod. Two 40-pin connectors al-
low the demonstration board to be connected to an expanded evaluation environment or to
external test equipment.
