Appendix B: Example of Configuration Values

The following example illustrates setting the configuration values in the PIC32 microcontroller on the
Cerebot MX3cK. 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 Cerebot MX3cK 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 chipKIT MPIDE system.
