Application Note 174 - Changing clocks on the ARM1136JF-S Core Module

# metadata.contentDescription
The CM1136JF-S user guide does not include all the details you need to change the clocks. This application note describes the clock circuits, gives step-by-step instructions how to change the frequencies, and includes two programs to set and measure the clocks. The calculator program assumes you have an Integrator/CP baseboard; it does not work with an Integrator/AP or no baseboard.
