Spread Spectrum [Disabled]
Use the Spread Spectrum 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.
