MNSECAM[1:0]
MNSECAM[1:0] Enable manual SECAM input detection.
0
Detection of SECAM input is automatic.*
2
Force the chip to assume input is not SECAM.
3
Force the chip to assume input is SECAM.
MNFSC[1:0] Enable manual Fsc detection.
0
Detection of Fsc frequency is automatic.*
2
Force chip to assume input Fsc is 4.43 MHz or 4.286 MHz.
3
Force chip to assume input Fsc is 3.58 MHz.
CTRACK
Chroma frequency tracking mode.
0
Chroma frequency tracking is based on the field rate and Fsc.*
1
Chroma frequency tracking is based on field rate only.
CDMLPF
Bypass the LPF in the chroma demodulator.
0
Chroma data pass through the LPF for color demodulation.*
1
Chroma data bypass the LPF. This setting is used for component video input.
SECDET
