-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.
