Î Spread Spectrum Mode [Disabled]
Use the Spread Spectrum Mode option to reduce the EMI. Excess EMI is generated
when the system clock generator pulses have extreme values. Spreading the pulse
spectrum modulates changes in the extreme values from spikes to flat curves, thus
reducing the EMI. This benefit may in some cases be outweighed by problems with
timing-critical devices, such as a clock-sensitive SCSI device.
