Appendix A: Example of Configuration Values
The following example illustrates setting the configuration values in the PIC32 microcontroller on the
Cerebot 32MX7. 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 32MX7 board. It sets the system clock for processor operation at 80Mhz,
and the peripheral bus at 10Mhz.
