Appendix B: Example of Configuration Values
The following example illustrates setting the configuration values in the PIC32 microcontroller on the ChipKIT MX3.
The microcontroller configuration should be done in a single source file in the project, and is typically done in the
‘main’ project source file. This example sets all configuration values to valid values for the ChipKIT MX3 board. It
sets the system clock for processor operation at 80Mhz, and the peripheral bus at 10Mhz. This example is for use
with MPLAB. Configuration variables are set by the boot loader in the MPIDE system.
