Inverting SSC profile - Setting for downspread per
SATA spec
Set to ’0’ when SSCmode = ’0’
Set to ’1’ when SSCmode = ’1’

1
Bypass the saw generator and pulse density modu-
lator and get increment from SSCMax (set SSCMax
to 45 [0x2D] when SSCBypass is set to 0)
NOTE: 1) In order to enable SSC generation, set register N.0044 to 0x2D, N.0045 to 0x14 and then reset the PLL by
writing register 0.0004 to 0x0 then 0xF.
