+Description:

+
+		=======	==========================================
+		Bits	Description
+		=======	==========================================
+		[7:0]	Sets clock spectrum spread percentage:
+			0x00=0.2% , 0x3F=10%
+			1 LSB = 0.1% increase in spread (for
+			settings 0x01 thru 0x1C)
+			1 LSB = 0.2% increase in spread (for
+			settings 0x1E thru 0x3F)
+		[8]	When set to 1, enables spread
+			spectrum clock
+		[9]	0: Triangle mode. FFC frequency
+			walks around the Fcenter in a linear
+			fashion
+			1: Random walk mode. FFC frequency
+			changes randomly within the SSC
+			(Spread spectrum clock) range
+		[10]	0: No white noise. 1: Add white noise
+			to spread waveform
+		[11]	When 1, future writes are ignored.
