sdp_scm_cti_en, Addr 90 (SDP), Address 0x0E[5]
This control is used to enable CTI in SECAM modes.
Function

The sdp_scm_cti_en bit enables an independent CTI block for SECAM modes. The SECAM signal is often clipped because of the LF-
emphasis filter that is used on the transmitter side. Once a signal is restored on the receiver side, its chroma transitions are slower.
