SECNTCH
[CP-CD]
Selection of Notch filter behavior in SECAM mode
‘00’: 4.406 MHz
‘01’: 4.250 MHz
‘10’: 4.33 MHz
‘11’: 4.406 / 4.25 dependent on transmitted color

CLRANGE
[CP-CD]
Chroma lock-range
‘00’: ± 425 Hz
‘01’: ± 463 Hz

LMOFST
[CP-CD]
Luminance Offset in color decoder during visible picture
‘00’: no offset
‘01’: −32 LSB ( −7.5 IRE)
‘10’:+32 LSB (+7.5 IRE)
‘11’: −16 LSB (−3.75 IRE)
Note: A 7.5 IRE offset is added during blanking in display processing. When
choosing ‘10’, the luminance offset is equal to the offset of the CVBS input as
in both picture and blanking the same 7.5 IRE offset is used.
