Input signals are cut off inside the Y/color difference
signal processing system. As a result, the signals which
were input to the RGB system are output. Range: 0-1,
0 = OFF, 1 = ON.

(pin 45). Range: 0-1, 0 = ON, 1 = OFF.

59) in YM ON block. Setting takes effect for both YS/
YM1 (pin 45) and YS/YM-2 (pin 49). Range: 0-1, 0 =
OFF : no muting, 1 = ON : muting.

= -4.2 dB, 29H = 0 dB, 3FH = +2.1 dB.
74 G-Drive: G channel drive gain control. Range: 0-63, 0
= -4.2 dB, 41 = 0 dB, 6.3 = +2.1 dB.
75 B-Drive: B channel drive gain control. Range: 0-63, 0
= -4.2 dB, 41 = 0 dB, 6.3 = +2.1 dB.
76 D-Col: Dynamic color ON/OFF switch. Range: 0 = OFF,
1 = ON.
77 Clpsw: Switch for selecting replacement pulse for color
difference input pin offset control. Range 0-1, 0 =
Pulse generated inside IC (replaced in period extend-
ing from rise of pulse which is input to HP-IN to the
fall of pulse in 1), 1 = Clamping pulse which has been
separated from SCP.
78 Clp-Msk: Switching of clamping pulse width in vari-
ous ways (refer to description of H-WIDTH register)
Gating at one of the SCP CLP pulses widths listed be-
low. Range: 0-3, 0 = CLP, in its original form, serves as
clamping pulse, 1 = Gating at SELH-OUT side of regis-
ter H-WIDTH, 2 = Gating at clamping pulse generation
block side of register H-WIDTH, 3 = Prohibited.
79 R-Cutoff: R channel cutoff control (Level control of
IkIN (pin 41) R channel reference pulse). Range: 0-
63, 0 = -9.1dB, 31 = 0 dB, 63 = +4.4 dB.
80 G-Cutoff: G channel cutoff control (Level control of
IkIN (pin 41) G channel reference pulse). Range: 0-
63, 0 = -9.1dB, 31 = 0 dB, 63 = +4.4 dB.
81 B-Cutoff: B channel cutoff control (Level control of
IkIN (pin 41) B channel reference pulse). Range: 0-
63, 0 = -9.1dB, 31 = 0 dB, 63 = +4.4 dB.
82 Abl-Mode: Switching of ABL mode. Range: 0-3, 0 =
Picture ABL only mode, 1 = Picture/brightness ABL
mode : Low, 2 = Picture/brightness ABL mode : Me-
dium, 3 = Picture/brightness ABL mode : High.
83 Abl-Th: Adjustment of threshold voltage for ABL-IN
(pin 44) input. Range 0-3, 0 = 1.3V, 3 = 3.3V.
81 Sub-Bright: Sub-brightness control. Setting for out-
put DC bias of RGBOUT. Range 0-63, 0 = -13 IRE, 31 =
CENTER, 63 = +13 IR.
84 Sub-Bright: Sub-brightness control.Range 0-63, set-
tings for output DC bias out RGB OUT . 0 = -13IRE, 31
= CENTER, 63 = +13IRE.
85 Hsep-Sel: Sync separation system setting (valid for
YG-IN (pin 26) input). Range: 0-1, 0 = Forced slice at
sync tip +0.15V level, 1 = Charging/discharging for
duty cycle.
86 Fix-Sync: Switch for setting sync identification cir-
cuit operation mode to auto or fixed. Range 0-3, 0 =
Automatic identification ( with priority sequence ), 1
= Independent H, V sync signals used, 2 = Composite
sync input used, 3 = Sync on Y, sync on Green inout
used.
87 V-Tc: Setting for V sync separation time constant.
Range: 0-3, 0 = 6 s, 1 = 8 s, 2 = 12 s, 3 = 18 s.
88 H-Width: Setting of output pulse width to HS-OUT
and clamping pulse generation block. When the pulse
width of the input sync signal is wider than the pulse
width in each data, the wider of the two pulses is
output. Range: 0-3.
89 Hs-Mask: Setting for whether H sync is to be added
in V sync at HS-OUT (pin 29) and SELH-OUT (pin 79).
Range: 0-1, 0 = Not added, 1 = Added.
