Function
Register 0E and 0F enable. When LOW, the functions of Register 0E and 0F
are disabled. When HIGH, Registers 0E and 0F are active. When Registers 0E
and 0F are enabled, Register 00 bit 3 is ignored. Register 0E bit 7 will read back
whatever value was written.
COMPOSITE D/A disable. When HIGH, the COMPOSITE D/A converter is
powered-down. When LOW, the D/A is enabled.
LUMA/CHROMA D/A disable. When HIGH, the LUMA and CHROMA D/A
converters are powered-down. When LOW, they are enabled.
Luminance processing enable. When FKREN is HIGH, the KEY input defines
the function of CVBS input data. When the KEY input is HIGH, CVBS data is
keyed over PD input data. When KEY is LOW, CVBS data is assumed to be
luminance data delayed by one When FKREN is LOW, the KEY input operates
normally, switching between CVBS and PD data.
Luminance ratio control bit. When LOW, 1/2 of current luminance and 1/2 of
field delayed luminance from the CVBS input are added to yield a new
combined luminance value. When RATIO is HIGH, 3/4 of current luminance is
added to 1/4 of the delayed luminance to produce a new luminance value.
Luminance-pass threshold. The difference between current luminance and
delayed luminance (from the CVBS inputs) is compared against a preset
threshold set by TFLK. When TFLK is LOW, the high threshold must be
exceeded to trigger the combining of current and delayed luminance (according
to RATIO). If the higher threshold is not exceeded, current luminance is passed
without modification. When TFLK is HIGH, a lower threshold is used to trigger
the combining of current and delayed luminance.
EH/SL offset control bit. When LOW, the true value of EH and SL is offset by
256. When HIGH, the true value for EH and SL is offset by 512.
NTSC/PAL color bars select. When HIGH, color bars with 100% white level are
selected. When LOW, color bars will have 75% white level.
