SSCmode
R/W
0
Selects position of spreading interpolator
0 = Interpolator in feedback path
1 = Interpolator in feedforward path
3
SSCCenter
R/W
0
Center spread instead of down/upspread
2
SSCInvert
R/W
0
Spread up instead of down
1
SSCPDMBypass
R/W
0
Do not use the pulse density modulator
0
SSCBypass
R/W
1
Bypass the saw generator and pulse density modu-
lator and get increment from SSCMax (set SSCMax
to 51 when SSCBypass is set to 0)

Override for charge pump programmability
0 = use value based on FB divider
1 = use value from PLLQpump
Values based on FB divider:
FBDIV[5:0] qpump[6:0]
11XXXX => 1111110
100000 => 0001110
100001 => 0000110
