 Spread Spectrum

The Spread Spectrum option allows you to reduce the EMI of your board by modulating the

signals it generates so that the spikes are reduced to flatter curves. It achieves this by varying the

frequency slightly so that the signal does not use any particular frequency for more than a moment.

The spread spectrum has the following configuration options
