When building the Digital PFC Application, the user can create an application that runs from internal Flash or External RAM. To select the type of application to build, open the digital_PFC.mcp project and choose the target build type; see Figure 3-1. A definition of the projects associated with these target build types may be viewed under the Targets tab of the project window. Figure 3-1. Target Build Selection The project may now be built by executing the Make command, as shown in Figure 3-2. This will build and link the Digital PFC Application and all needed Metrowerks and Processor Expert libraries. Figure 3-2.

For more help with these commands, refer to the CodeWarrior tutorial documentation in the following file, located in the CodeWarrior installation directory: <...>\CodeWarrior Manuals\PDF\Targeting_56800E.pdf If the Flash target is selected, CodeWarrior will automatically program the device’s internal Flash with the executable generated during Build. If the External RAM target is selected, the executable will be loaded to off-chip RAM. Once Flash has been programmed with the executable, the EVM target system may be run in a stand-alone mode from Flash. To do this, set the JG9 jumper in the 1-2 configuration to disable the parallel port, and press the RESET button. To enable the PFC conversion, set the RUN/STOP switch to the RUN position. If this switch was in the RUN position before the application started, move it to the STOP position first, then back to the RUN position. The USER LED should light continuously when the PFC conversion is enabled. To disable the PFC conversion, move the RUN/STOP switch to the STOP position, causing the USER LED to blink again.
