Bit Description
ADC1_SW [3:0]. Manual muxing control
for ADC1.
ADC2_SW [3:0]. Manual muxing control
for ADC2.
Reserved.
ADC_SW_MAN_EN. This bit enables manual
setting of the input signal muxing.
FCL [12:8]. The number of 27 MHz clock
cycles between successive vsyncs.
Reserved.
FCL[7:0]. See FCL [12:8].
LB_TH [4:0]. These bits set the threshold
value that determines if a line is black.
Reserved.
LB_EL [3:0]. These bits program the end
line of letterbox detection (end of field).
LB_SL [3:0]. These bits program the start
line of letterbox detection (start of field).
ST_NOISE [10:8]. Sync tip noise measurement.
ST_NOISE_VLD.
Reserved.
ST_NOISE [7:0]. See ST_NOISE [10:0].
SD_OFF_CB [7:0]. These bits adjust the hue
by selecting the offset for the Cb channel.
SD_OFF_CR [7:0]. These bits adjust the hue
by selecting the offset for the Cr channel.
SD_SAT_CB [7:0]. These bits adjust the
saturation of the picture by affecting gain on
the Cb channel.
