Description:
(RO) Presents SSC (spread spectrum clock) information for EMI
(Electro magnetic interference) control. This is a bit mask.
======= ==========================================
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.
