137 ======= ==========================================
138 Bits Description
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.
