Function

DEM_CKILL_LVL

[2:0]

Reserved. Must be set to 000. Chroma Killer Hysteresis Level

The chroma kill mechanism is by default in automatic mode (see ddeccontd[7:0] register). The color is killed

on the output when no chroma standard is recognised. This register offers an additional killer feature when

in automatic mode. The chroma is killed when the burst amplitude is under the chroma killer automatic level.

The chroma is restaured when the chroma burst amplitude is above the threshold plus the programmed

hysteresis. When the chroma burst amplitude < dem_ckill_lvl[4:0], the chroma is killed. When the chroma is

killed and the chroma burst amplitude > dem_ckill_lvl[4:0] + dem_ckill_lvl[7:5], the chroma is no longer

killed.
