Pedestal Configuration in SDP Modes

6.3.2
The following controls dictate which standards the SDP core expects to have a pedestal. Standards that are expected to have a pedestal are
clamped to the back porch level.
sdp_pal_ped_en, Addr 90 (SDP), Address 0x01[0]
This control is used to force the part to assume that the corresponding standard has a pedestal. Standards with a pedestal are clamped to
the pedestal level; standards without a pedestal are clamped to the back porch level.

0 
sdp_secam_ped_en, Addr 90 (SDP), Address 0x01[6]
This control is used to force the part to assume that the corresponding standard has a pedestal. Standards with a pedestal are clamped to
the pedestal level; standards without a pedestal are clamped to the back porch level.

sdp_n443_ped_en, Addr 90 (SDP), Address 0x01[5]
This control is used to force the part to assume that the corresponding standard has a pedestal. Standards with a pedestal are clamped to
the pedestal level; standards without a pedestal are clamped to the back porch level.

sdp_pal60_ped_en, Addr 90 (SDP), Address 0x01[4]
This control is used to force the part to assume that the corresponding standard has a pedestal. Standards with a pedestal are clamped to
the pedestal level; standards without a pedestal are clamped to the back porch level.

sdp_palcn_ped_en, Addr 90 (SDP), Address 0x01[3]
This control is used to force the part to assume that the corresponding standard has a pedestal. Standards with a pedestal are clamped to
the pedestal level; standards without a pedestal are clamped to the back porch level.
