3 Hardware Resource Mapping

3.1 Resource Allocation

Figure 5 shows the various stages of the board in a circuit diagram format and illustrates the major

connections and feedback values being mapped to the C2000 MCU. Table 2 lists these resources. It is

important to note that not all resources are available on every C2000 MCU. For more detailed information,

see the schematics and device-specific data sheets.
