139		=======	==========================================
140		[7:0]	Sets clock spectrum spread percentage:
141			0x00=0.2% , 0x3F=10%
142			1 LSB = 0.1% increase in spread (for
143			settings 0x01 thru 0x1C)
144			1 LSB = 0.2% increase in spread (for
145			settings 0x1E thru 0x3F)
146		[8]	When set to 1, enables spread
147			spectrum clock
148		[9]	0: Triangle mode. FFC frequency
149			walks around the Fcenter in a linear
150			fashion
151			1: Random walk mode. FFC frequency
152			changes randomly within the SSC
153			(Spread spectrum clock) range
154		[10]	0: No white noise. 1: Add white noise
155			to spread waveform
156		[11]	When 1, future writes are ignored.
