CAR_DET
R/W
The carrier detector freezes the PLL in case of a
picture carrier overmodulation (especially when the
picture carrier is very low or disappears). In
addition, the picture carrier DTO value is forced to
an optimal one to avoid picture carrier phase drift.
To adjust the threshold see CAR_DET_LVL.
