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.
