  ======= ==========================================
  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.
