0140 [7:0] Sets clock spectrum spread percentage:
0141 0x00=0.2% , 0x3F=10%
0142 1 LSB = 0.1% increase in spread (for
0143 settings 0x01 thru 0x1C)
0144 1 LSB = 0.2% increase in spread (for
0145 settings 0x1E thru 0x3F)
0146 [8] When set to 1, enables spread
0147 spectrum clock
0148 [9] 0: Triangle mode. FFC frequency
0149 walks around the Fcenter in a linear
0150 fashion
0151 1: Random walk mode. FFC frequency
0152 changes randomly within the SSC
0153 (Spread spectrum clock) range
0154 [10] 0: No white noise. 1: Add white noise
0155 to spread waveform
0156 [11] When 1, future writes are ignored.
