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 out-
weighed by problems with timing-critical devices, such as a clock-sensitive SCSI device.
